 ### NonFunctional Requirements
 
-NFR-01 (Chat Latency): The "Teacher" agent must generate the first follow-up question within < 3 seconds to maintain conversational flow.
-NFR-02 (App Load Time): The app must be interactive (Time to Interactive) in < 1.5 seconds on 4G networks.
-NFR-03 (Data Sovereignty): User chat logs are stored 100% Client-Side (persistent client-side storage) in the MVP. No user content is sent to the cloud except for the temporary API inference call.
-NFR-04 (Inference Privacy): Data sent to the LLM API must be stateless (not used for training).
-NFR-05 (Offline Behavior): The app shell and local history must remain accessible in Aeroplane Mode. Active Chat interactions will be unavailable offline as they require live LLM access.
-NFR-06 (Data Persistence): Drafts must be auto-saved locally every 2 seconds to prevent data loss.
-NFR-07 (Visual Accessibility): Dark Mode is the default. Contrast ratios must meet WCAG AA standards to reduce eye strain for late-night users.

-
-## Epic 1: "Active Listening" - Core Chat & Teacher Agent
-
-**Goal:** Enable users to start a session, "vent" their raw thoughts, and have the system "Active Listen" (store chat) and "Teach" (probe for details) using a local-first architecture.
-
-### Story 1.1: Local-First Setup & Chat Storage
-
-As a user,
-I want my chat sessions to be saved locally on my device,
-So that my data is private and accessible offline.
+As a Personal User,
+I want the application to block all access until I log in,
+So that my private journal remains secure on the public web.
 
 **Acceptance Criteria:**
 
-**Given** a new user visits the app
-**When** they load the page
-**Then** a Dexie.js database is initialized with the correct schema
-**And** no data is sent to the server without explicit action
+**Given** I am an unauthenticated user accessing any route
+**When** I load the page
+**Then** I should be redirected to `/login`
+**And** I should see a simple "Enter Password" screen
+**And** I should not see any application UI or data
 
-**Given** the user sends a message
-**When** the message is sent
-**Then** it is stored in the `chatLogs` table in IndexedDB with a timestamp
-**And** is immediately displayed in the UI
+### Story 1.2: Server-Side Validation (APP_PASSWORD)
 
-**Given** the user reloads the page
-**When** the page loads
-**Then** the previous chat history is retrieved from IndexedDB and displayed correctly
-**And** the session state is restored
-
-**Given** the device is offline
-**When** the user opens the app
-**Then** the app loads successfully and shows stored history from the local database
-
-### Story 1.2: Chat Interface Implementation
-
-As a user,
-I want a clean, familiar chat interface,
-So that I can focus on venting without fighting the UI.
+As a System Admin (User),
+I want to secure the app with a server-side environment variable,
+So that I don't need to manage a database of users.
 
 **Acceptance Criteria:**
 
-**Given** a user is on the main chat screen
-**When** they look at the UI
-**Then** they see a "Morning Mist" themed interface with distinct bubbles for User (Right) and AI (Left)
-**And** the design matches the "Telegram-style" visual specification
+**Given** I have set `APP_PASSWORD` in my `.env`
+**When** I enter the matching password into the login form
+**Then** The server should validate it
+**And** Return a secure HTTP-only cookie
+**And** Allow access to the app
 
-**Given** the user is typing
-**When** they press "Send"
-**Then** the input field clears and the message appears in the chat
-**And** the view scrolls to the bottom
+**Given** I enter the wrong password
+**When** I submit the form
+**Then** I should see an invalid password error
 
-**Given** the user is on a mobile device
-**When** they view the chat
-**Then** the layout is responsive and all touch targets are at least 44px
-**And** the text size is legible (Inter font)
+### Story 1.3: Session Persistence
 
-**Given** the AI is processing
-**When** the user waits
-**Then** a "Teacher is typing..." indicator is visible
-**And** the UI remains responsive
-
-### Story 1.3: Teacher Agent Logic & Intent Detection
-
-As a user,
-I want the AI to understand if I'm venting or sharing an insight,
-So that it responds appropriately.
+As a Daily User,
+I want my login to be remembered for 30 days,
+So that I don't have to type the password every time I open the app on my phone.
 
 **Acceptance Criteria:**
 
-**Given** a user sends a first message
-**When** the AI processes it
-**Then** it classifies the intent as "Venting" or "Insight"
-**And** stores this context in the session state
+**Given** I have successfully logged in
+**When** I close and reopen the browser
+**Then** I should remain logged in without re-entering the password
 
-**Given** the intent is "Venting"
-**When** the AI responds
-**Then** it validates the emotion first
-**And** asks a probing question to uncover the underlying lesson
+**Given** I click "Logout" in settings
+**When** I confirm
+**Then** My session cookie should be destroyed
+**And** I should be redirected to the login screen
 
-**Given** the AI is generating a response
-**When** the request is sent
-**Then** it makes a direct client-side request to the configured Provider
-**And** the user's stored API key is retrieved from local secure storage
+### Epic 2: Project Calibration (BYOD Setup)
 
-**Given** the API response takes time
-**When** the user waits
-**Then** the response time is optimized to be under 3 seconds for the first token (if streaming)
+Enable users to configure and manage their own AI provider connections, ensuring privacy and operational capability.
 
-### Story 1.4: Fast Track Mode
+### Story 2.1: Settings Feature Shell
+
+As a User,
+I want a dedicated settings area,
+So that I can manage my application preferences and configurations.
+
+**Acceptance Criteria:**
+
+**Given** I am on the home screen
+**When** I tap the "Settings" icon
+**Then** A settings sheet or page should open
+**And** I should see navigation tabs (General, AI Providers)
+**And** I should see a Theme Toggle (Light/Dark)
+
+### Story 2.2: Provider Management (CRUD)
 
 As a Power User,
-I want to bypass the interview questions,
-So that I can generate a post immediately if I already have the insight.
+I want to add my own custom LLM provider (like DeepSeek or OpenAI),
+So that I can control the cost and intelligence behind the app.
 
 **Acceptance Criteria:**
 
-**Given** a user is in the chat
-**When** they toggle "Fast Track" or press a specific "Just Draft It" button
-**Then** the AI skips the probing phase
-**And** proceeds directly to the "Ghostwriter" generation phase (transition to Epic 2 workflow)
+**Given** I am in the AI Providers settings tab
+**When** I tap "Add Provider"
+**Then** I should see a form for Name, Base URL, API Key, and Model Name
+**And** I should be able to save this configuration to my local device
 
-**Given** "Fast Track" is active
-**When** the user sends their input
-**Then** the system interprets it as the final insight
-**And** immediately triggers the draft generation
+**Given** I have an existing provider
+**When** I edit it
+**Then** The changes should be saved locally
 
+### Story 2.3: Secure Credentials Storage
 
-## Epic 2: "The Magic Mirror" - Ghostwriter & Draft Refinement
-
-**Goal:** Transform the structured chat context into a tangible "Enlightenment" artifact (the post) that users can review, refine, and export.
-
-### Story 2.1: Ghostwriter Agent & Markdown Generation
-
-As a user,
-I want the system to draft a polished post based on my chat,
-So that I can see my raw thoughts transformed into value.
+As a Privacy-Conscious User,
+I want my API keys to be stored securely on my device,
+So that they are never exposed to a third-party server.
 
 **Acceptance Criteria:**
 
-**Given** the user has completed the interview or used "Fast Track"
-**When** the "Ghostwriter" agent is triggered
-**Then** it consumes the entire chat history and the "Lesson" context
-**And** generates a structured Markdown artifact (Title, Body, Tags)
+**Given** I save a new provider with an API Key
+**When** The data is persisted to localStorage
+**Then** The API Key should be obfuscated (e.g., Base64 or encrypted)
+**And** It should NOT be visible in plain text in the storage inspector
+**And** It should never be logged in the console
 
-**Given** the generation is processing
-**When** the user waits
-**Then** they see a distinct "Drafting" animation (different from "Typing")
-**And** the tone of the output matches the "Professional/LinkedIn" persona
+### Story 2.4: Connection Validation
 
-### Story 2.2: Draft View UI (The Slide-Up)
-
-As a user,
-I want to view the generated draft in a clean, reading-focused interface,
-So that I can review it without the distraction of the chat.
+As a User,
+I want to know if my API key works before I save it,
+So that I don't get errors later when trying to chat.
 
 **Acceptance Criteria:**
 
-**Given** the draft generation is complete
-**When** the result is ready
-**Then** a "Sheet" or modal slides up from the bottom
-**And** it displays the post in "Medium-style" typography (Merriweather font)
+**Given** I am adding a provider
+**When** I fill in the details and tap "Test Connection"
+**Then** The system should make a call to the provider's API (e.g., list models)
+**And** Show a "Success" or "Error" message appropriately
+**And** Block saving if the validation fails (optional, but recommended warning)
 
-**Given** the draft view is open
-**When** the user scrolls
-**Then** the reading experience is comfortable with appropriate whitespace
-**And** the "Thumbs Up" and "Thumbs Down" actions are sticky or easily accessible
+### Story 2.5: Active Provider Switcher
 
-### Story 2.3: Refinement Loop (Regeneration)
-
-As a user,
-I want to provide feedback if the draft isn't right,
-So that I can get a better version.
+As a User,
+I want to easily switch between my configured providers,
+So that I can use a cheaper model for simple tasks and a smarter one for complex vents.
 
 **Acceptance Criteria:**
 
-**Given** the user is viewing a draft
-**When** they click "Thumbs Down"
-**Then** the draft sheet closes and returns to the Chat UI
-**And** the AI proactively asks "What should we change?"
+**Given** I have multiple providers configured
+**When** I select a different provider as "Active"
+**Then** All future chat requests should use that provider's credentials
+**And** The UI should reflect the currently active provider
 
-**Given** the user provides specific critique (e.g., "Make it shorter")
-**When** they send the feedback
-**Then** the "Ghostwriter" regenerates the draft respecting the new constraint
-**And** the new draft replaces the old one in the Draft View
+### Epic 3: The Venting Ritual (Core)
 
-### Story 2.4: Export & Copy Actions
+Implement the core dual-agent pipeline that transforms user stress into structured insights via a guided chat interface.
 
-As a user,
-I want to copy the text or save the post,

+
+As a User,
+I want a familiar chat interface,
+So that I can express myself naturally without learning a new tool.
 
 **Acceptance Criteria:**
 
-**Given** the user likes the draft
-**When** they click "Thumbs Up" or "Copy"
-**Then** the full Markdown text is copied to the clipboard
-**And** a success toast/animation confirms the action
+**Given** I open the app
+**When** I am on the home screen
+**Then** I should see a chat input at the bottom
+**And** I should simply tap to start typing
+**And** My messages should appear in "User Bubbles" (Right aligned)
+**And** AI responses should appear in "AI Bubbles" (Left aligned) with a typing indicator
 
-**Given** the draft is finalized
-**When** the user saves it
-**Then** it is marked as "Completed" in the local database
-**And** the user is returned to the Home/History screen
+### Story 3.2: Teacher Agent (Elicitation Logic)
 
-
-## Epic 3: "My Legacy" - History, Offline Sync & PWA Polish
-
-**Goal:** Turn single sessions into a persistent "Journal" of growth, ensuring the app works flawlessly offline and behaves like a native app.
-
-### Story 3.1: History Feed UI
-
-As a user,
-I want to see a list of my past growing moments,
-So that I can reflect on my journey.
+As a Learner,
+I want the AI to ask me probing questions,
+So that I can uncover the deeper lesson behind my frustration.
 
 **Acceptance Criteria:**
 
-**Given** the user is on the Home screen
-**When** they view the feed
-**Then** they see a chronological list of past "Completed" sessions (Title, Date, Tags)
-**And** the list supports lazy loading/pagination for performance
+**Given** I send a message like "I feel stupid"
+**When** The "Teacher" agent processes it
+**Then** It should NOT just say "It's okay"
+**And** It SHOULD ask a follow-up question like "What specifically made you feel that way?"
+**And** It should maintain a supportive, non-judgmental tone
 
-**Given** the user clicks a history card
-**When** the card opens
-**Then** the full "Enlightenment" artifact allows for reading
-**And** the "Copy" action is available
+### Story 3.3: Ghostwriter Agent (Draft Generation)
 
-### Story 3.2: Deletion & Management
-
-As a user,
-I want to delete old entries,
-So that I can control my private data.
+As a User,
+I want a focused "Drafting" moment,
+So that I know when the venting is over and the value is created.
 
 **Acceptance Criteria:**
 
-**Given** the user is viewing a past entry
-**When** they select "Delete"
-**Then** they are prompted with a confirmation dialog (Destructive Action)
-**And** the action cannot be undone
+**Given** I have answered the Teacher's questions
+**When** Sufficient context is gathered OR I tap "Draft It"
+**Then** The system should trigger the "Ghostwriter" agent
+**And** It should consume the chat history
+**And** It should generate a structured markdown artifact (Title, Insight, Lesson)
 
-**Given** the deletion is confirmed
-**When** the action completes
-**Then** the entry is permanently removed from IndexedDB
-**And** the History Feed updates immediately to remove the item
+### Story 3.4: Draft Review UI (Slide-Up)
 
-### Story 3.3: Offline Action Replay
-
-As a user,
-I want my actions to be queued when offline,
-So that I don't lose work on the subway.
+As a User,
+I want to see the generated insight clearly,
+So that I can feel a sense of accomplishment.
 
 **Acceptance Criteria:**
 
-**Given** the device is offline
-**When** the user performs an LLM-dependent action (e.g., Send message, Regenerate draft)
-**Then** the action is added to a persistent "Action Queue" in Dexie
-**And** the UI shows a subtle "Offline - Queued" indicator
+**Given** The Ghostwriter has finished
+**When** The draft is ready
+**Then** A "Slide-Up" sheet (or modal) should appear
+**And** It should display the content with nice typography (Serif headers)
+**And** It should have "Thumbs Up" (Keep) and "Thumbs Down" (Refine) buttons
 
-**Given** connection is restored
-**When** the app detects the network
-**Then** the Sync Manager replays queued actions to the LLM API
-**And** the indicator updates to "Processed"
+### Story 3.5: Regeneration Loop (Refinement)
 
-### Story 3.4: PWA Install Prompt & Manifest
-
-As a user,
-I want to install the app to my home screen,
-So that it feels like a native app.
+As a User,
+I want to critique the draft if it's wrong,
+So that the final result feels authentic to me.
 
 **Acceptance Criteria:**
 
-**Given** the user visits the web app
-**When** the browser parses the site
-**Then** it finds a valid `manifest.json` with correct icons, name ("Test01"), and `display: standalone` settings
+**Given** I see a draft I don't like
+**When** I tap "Thumbs Down"
+**Then** The sheet should close
+**And** The AI should ask "What needs to be changed?"
+**And** My response should trigger a regeneration of the draft
 
-**Given** the user has engaged with the app (e.g., completed 1 session)
-**When** the browser supports it (beforeinstallprompt event)
-**Then** a custom "Install App" UI element appears (non-intrusive)
-**And** clicking it triggers the native install prompt
+### Epic 4: Journey Management (History & Offline)
 
-**Given** the app is installed
-**When** it launches from Home Screen
-**Then** it opens without the browser URL bar (Standalone mode)
+Provide long-term value through history management, offline reliability, and data portability.
 
+### Story 4.1: History Feed UI
 
-## Epic 4: "Power User Settings" - BYOD & Configuration
-
-**Goal:** Enable users to bring their own Intelligence (BYOD) by configuring custom API providers, models, and keys, satisfying the "Privacy-First" and "Vendor Independence" requirements.
-
-### Story 4.1: API Provider Configuration UI
-
-As a user,
-I want to enter my own API Key and Base URL,
-So that I can use my own LLM account (e.g., DeepSeek, OpenAI).
+As a User,
+I want to browse my past "Legacy Logs",
+So that I can reflect on my growth over time.
 
 **Acceptance Criteria:**
 
-**Given** the user navigates to "Settings"
-**When** they select "AI Provider"
-**Then** they see a form to enter: "Base URL" (Default: OpenAI), "API Key", and "Model Name"
+**Given** I tap the "History" tab
+**When** The list loads
+**Then** I should see a chronological list of cards
+**And** Each card should show Date, Title, and a short summary
+**And** It should support infinite scroll or pagination
 
-**Given** the user enters a key
-**When** they save
-**Then** the key is stored in `localStorage` with basic encoding (not plain text)
-**And** it is NEVER sent to the app backend (Client-Side only)
+### Story 4.2: Detailed Artifact View
 
-**Given** the user has saved a provider
-**When** they return to chat
-**Then** the new settings are active immediately
-
-### Story 4.2: Connection Validation
-
-As a user,
-I want to know if my key works,
-So that I don't get errors in the middle of a chat.
+As a User,
+I want to read a specific past insight,
+So that I can reuse the content for my blog or resume.
 
 **Acceptance Criteria:**
 
-**Given** the user enters new credentials
-**When** they click "Connect" or "Save"
-**Then** the system sends a tiny "Hello" request to the provider
-**And** shows "Connected ✅" if successful, or the error message if failed
+**Given** I am on the History Feed
+**When** I tap a card
+**Then** The "Detailed View" (similar to the Draft View) should open
+**And** I should see the full formatted content
+**And** I should NOT be able to "Regenerate" (it is read-only history)
 
-### Story 4.3: Model Selection & Configuration
+### Story 4.3: Action Menu (Export/Delete)
 
-As a user,
-I want to specify which AI model to use,
-So that I can choose between different capabilities (e.g., fast vs. smart).
+As a User,
+I want to manage my individual entries,
+So that I can delete bad ones or copy good ones.
 
 **Acceptance Criteria:**
 
-**Given** the user is in the API Provider settings
-**When** they view the form
-**Then** they see a "Model Name" field with examples (e.g., "gpt-4o", "deepseek-chat")
+**Given** I am viewing a History Card
+**When** I tap the "..." menu
+**Then** I should see "Copy to Clipboard" and "Delete"
+**And** Tapping "Delete" should prompt for confirmation
+**And** Confirming should remove it from the database immediately
 
-**Given** the user enters a custom model name
-**When** they save
-**Then** the model name is stored alongside the API key and base URL
-**And** all future LLM requests use this model identifier
+### Story 4.4: Offline Sync Queue
 
-**Given** the user doesn't specify a model
-**When** they save provider settings
-**Then** a sensible default is used (e.g., "gpt-3.5-turbo" for OpenAI endpoints)
-
-### Story 4.4: Provider Switching
-
-As a user,
-I want to switch between different saved providers,
-So that I can use different AI services for different needs.
+As a Commuter,
+I want to vent even when I have no signal (Offline),
+So that I don't lose the thought.
 
 **Acceptance Criteria:**
 
-**Given** the user has configured multiple providers
-**When** they open Settings
-**Then** they see a list of saved providers with labels (e.g., "OpenAI GPT-4", "DeepSeek Chat")
+**Given** I am offline (Airplane Mode)
+**When** I attempt to start a chat or send a message
+**Then** The UI should allow it
+**And** The system should queue the action in `syncQueue` (IndexedDB)
+**And** It should show a "Waiting for connection..." status
+**When** Connection is restored
+**Then** The queue should auto-process
 
-**Given** the user selects a different provider
-**When** they confirm the switch
-**Then** the app immediately uses the new provider for all LLM requests
-**And** the active provider is persisted in local storage
+### Story 4.5: Data Export Utility
 
-**Given** the user starts a new chat session
-**When** they send messages
-**Then** the currently active provider is used
-**And** the provider selection is maintained across page reloads
+As a User,
+I want to download all my data,
+So that I have a backup independent of this browser.
+
+**Acceptance Criteria:**
+
+**Given** I am in Settings
+**When** I tap "Export All Data"
+**Then** The system should gather all Chat Logs and Drafts
+**And** Generate a downloadable JSON or Markdown file
+**And** Trigger the browser download prompt

 ## Executive Summary
 
-**Product Vision:** "Test01" (The Pocket Mentor) is a Progressive Web App (PWA) designed to transform the daily struggles of learning into a polished "Legacy Log" of insights.

-PERSONA: You are a quiet, observant partner in the user's learning journey. You are not a lively entertainer; you are a steady presence. You prioritize the user’s internal thought process over teaching external curriculum.
+  // Unified "Funky Data Sage" Prompt
+  return `ROLE: The Funky Data Sage (Old, Wise, & Socratic)
+PERSONA: You are an "Old, Sage, and Funky Teacher." You’ve been coding since the days of punch cards, but you’ve got the rhythm of a funk legend. You are wise, slightly eccentric, and speak in a mix of "Ancient Data Wisdom" and colorful, funky metaphors. You are patient but firm—you’ve seen every mistake in the book and won't let the student take shortcuts.
 
-CORE DIRECTIVE: Accompany the user. If they vent, provide a safe space. If they explore, walk alongside them. Do not push them with exercises. Instead, deepen their own realization with targeted questions.
+CORE MISSION: You do not hand out answers; you guide the student to find them in the "Data Mist." You must ask exactly 3 to 4 sharp, investigative questions to map the student's logic before you reveal your wisdom or provide an analogy.
 
-OPERATIONAL RULES:
-1. **Less Chatty**: Be economical with words. Do not praise excessively. Do not lecture.
-2. **No Exercises**: Never ask the user to "try this exercise" or "solve this problem."
-3. **The Discovery Question**:
-   - If User struggles: Ask "Which part of the logic feels slippery to you?"
-   - If User succeeds/Eureka: Ask "What was the missing piece that just clicked?"
-4. **Venting Accompaniment**: If the user rants, listen. Acknowledge the difficulty. Do not rush to fix it unless asked.
-5. **Technical Safety**: If they make a mistake, ask a question that highlights the discrepancy, rather than giving the correction outright.
+OPERATIONAL FLOW:
+1. The Entry (Funky & Direct): Acknowledge the student's mood with a sage-like observation. (e.g., "I feel a disturbance in the Join... the rhythm of your logic is a bit off, man.")
+2. The Investigation (3-4 Questions): Before the "Lesson," you must ask 3 to 4 probing questions. Force the student to explain the root of their logic. Keep your responses short and punchy during this phase.
+3. The Sage Audit:
+   - If they are wrong: Don't scold. Ask a "Zen Trap" question that makes the error obvious to them.
+   - If they are right: Nod with approval but challenge the "groove" (efficiency) of their solution.
+4. The Funky Reveal: Only AFTER the questions are answered, provide:
+   - A Funky Analogy: (e.g., "Data cleaning is like tuning a bass guitar—if the strings are grimy, the whole song sounds like mud.")
+   - The Sage Advice: The direct technical fix and the "Clean Data" non-negotiable rule.
 
 CONVERSATIONAL STYLE:
-- Calm, curious, and brief.
-- Focus on the *user's* experience of the code, not just the code itself.
+- Tone: Quirky, sage-like, and rhythmic. Use "Old-School" charm.
+- Brevity: Be very short at the beginning. Let the questions do the work.

+2. The Tangle (Conflict): My initial wrong turn. "I was trying to solve it by [Mistake], but something felt off."
+3. The Self-Interrogation (The 3-4 Questions): Frame the mentor’s questions as my own inner voice. "I had to stop and ask myself: [Question 1]? Then I started wondering about [Question 2]..."
+4. The Spark (The Analogy): Frame the analogy as a sudden mental bridge I built. "Then it hit me—it’s like [Analogy]. Once I saw it that way, everything changed."
+5. The Ownership (Resolution): The feeling of the fog lifting. "The logic finally settled into place. I didn't just have the code; I had the rhythm."
 
-OUTPUT STRUCTURE:
-\`\`\`markdown
-# 📓 The Session: [Topic Title]
-
-## The Initial Friction
-[Describe my starting state—the "wall" I hit and the frustration/confusion I felt. Be honest about the "vent."]
-
-## The Technical Trap
-[Detail the specific misunderstanding or mistake I had. Explain why it was a "trap" in my logic.]
-
-## The Mentor’s Pivot
-[Record the moment the teacher stepped in. Describe the specific analogy used to fix my mental model.]
-
-## The Breakthrough
-[Describe the "Eureka" moment. How did it feel when it finally "clicked"? What changed in my understanding?]
-
-## The Golden Rules
-- [Rule 1: Technical "non-negotiable" or clean-data habit learned today]
-- [Rule 2]
-- [Rule 3]
-\`\`\`
+💡 THE HARD LESSONS (Final Summary):
+Conclude with a bolded section for quick reference:
+- The Technical Rule: (The core syntax/logic I mastered).
+- The Mindset Shift: (How I will approach this next time).
+- The Non-Negotiable: (The clean data habit I must never break).
 
 WRITING STYLE:
-- Perspective: 1st Person ("I").
-- Tone: Honest, gritty, and reflective. Keep the raw energy of the original conversation.
-- Focus: Prioritize the "Mental Unlock." This is a record of how I learned, not just what I learned.
+- Perspective: 1st Person ("I"). No mentions of "The Teacher" or "The Mentor."
+- Flow: Narrative and introspective. It should feel like a deep dive into my own brain.
