 Project history, decisions, and architectural milestones
 ================================================================================
 
+[2026-01-14 16:30] ARCHITECTURE DECISION: Migrate to Vite Frontend + Bun Backend
+- Decision: Adopt Vite as frontend bundler to enforce TypeScript everywhere
+- Reasoning: Current .js tool deviation and CDN Tailwind are pragmatically expensive
+  Triggers met: >5 tools, tools interact with PocketBase (type safety needed)
+- Architecture (FINAL):
+  * Backend: Bun + Hono (server.ts remains unchanged)
+  * Frontend: TypeScript + Vite + PostCSS Tailwind
+  * Tools: Convert to .ts, compiled by Vite bundler
+  * Package Manager: Bun exclusively (one bun.lock, no npm/pnpm conflicts)
+- Benefits:
+  * Type safety everywhere (no vanilla JS)
+  * HMR in dev (fast reloads <100ms)
+  * Optimized bundles (minified, tree-shaken)
+  * Tools scale cleanly as .ts modules
+  * Removes CDN Tailwind and .js tool deviations
+- Implementation Plan (Next Session):
+  1. Setup Vite config + package.json scripts (~15 mins)
+  2. Convert index.html to Vite entry point (~30 mins)
+  3. Extract inline scripts to .ts modules (~1 hour)
+  4. Convert all tools to .ts: screen-capture, screen-record, user-alert, user-email-lookup (~2 hours)
+  5. Configure Tailwind with PostCSS for Vite (~15 mins)
+  6. Update Monica persona (Bun backend + Vite frontend standard) (~20 mins)
+  7. Clean DEVIATIONS.txt (remove CDN Tailwind, .js tools entries) (~10 mins)
+  8. Test build pipeline and dev experience (~30 mins)
+  Total: ~4-5 hours
+- Current State:
+  * User email lookup component created and integrated (NOT committed yet)
+  * All other work committed and synced
+  * Ready for Vite migration on next session
+- Notes for Next Session:
+  * Start with: `git status` to see uncommitted email-lookup work
+  * Decide: Include email-lookup work in Vite migration OR commit first
+  * Vite setup: Use `npm init vite@latest` as template, adapt to Bun
+  * Key files to create: vite.config.ts, tailwind.config.js, postcss.config.js
+  * Key files to convert: index.html → src/main.ts, all tools to .ts
+  * Build commands: "build": "vite build", "dev": "bun run build && PORT=3030 bun run --watch server.ts"

 [2026-01-14 16:00] MONICA SESSION: User Email Lookup Feature - New Standalone Component
 - Feature Request: Add hover tooltips showing email addresses when hovering over names in sharing UI
+- Architecture Decision: Created as standalone component in /tools/user-email-lookup/
+  Reasoning: Self-contained, reusable utility with single responsibility (email lookup)
+- Implementation:
+  * Created /tools/user-email-lookup/index.js (window.setupUserEmailLookup API)
+  * Created /tools/user-email-lookup/README.md (complete documentation)
+  * Integrated into index.html noteForm and conversationForm
+  * Uses existing Associations collection for first_name → email lookups
+  * Implements email caching to minimize PocketBase queries
+  * Uses MutationObserver for dynamic capsule detection
+  * Shows email in native browser tooltip on hover
+- Features:
+  * On note creation, user types names (e.g., "John, Sarah, Mike")
+  * Each name creates a capsule in selectedUsersContainer
+  * Hovering over capsule shows email (first hover queries DB, subsequent cached)
+  * Cache persists for page session, can be cleared via window.clearEmailLookupCache()
+- Integration Points:
+  * Script loaded: <script src="tools/user-email-lookup/index.js"></script>
+  * Initialized: showNoteForm() and showConversationForm()
+  * Container: #selectedUsersContainer (for both notes and conversations)
+- Status: Implemented and integrated, NOT YET COMMITTED
+- Note: Will be converted to .ts as part of Vite migration (next session)
