Phase 08 Plan 01: Performance Plumbing & Design Tokens Summary

queueMicrotask notification coalescing in library store, 150ms debounced search input, and design token CSS custom properties for icon/type sizing

Accomplishments

Library store notify() coalesces 8+ notifications during scan invalidation into a single subscriber notification per microtask tick
Search input debounces store propagation by 150ms while maintaining instant visual feedback and instant clear
Design token file defines --yj-icon-sm/md/lg and --yj-text-xs/sm/md/lg/xl CSS custom properties for consistent sizing

Task Commits

Each task was committed atomically:

Task 1: Add queueMicrotask debouncing to library store and search input debounce - 3bf66ed (perf)
Task 2: Define design token CSS custom properties for icon sizes and type scale - 1444a66 (feat)

Files Created/Modified

frontend/src/store/library-store.ts - Added notifyScheduled flag and queueMicrotask coalescing in notify()
frontend/src/components/search-bar/search-bar.ts - Added 150ms debounce timer for search store propagation
frontend/src/styles/tokens.css.ts - New design token file with icon sizes and type scale custom properties

Decisions Made

Used queueMicrotask over setTimeout for notification coalescing — synchronous microtask batching is more predictable and lower latency than macrotask scheduling
150ms debounce with instant clear on empty input — balances responsiveness with avoiding unnecessary computation; empty clears are immediate for snappy UX
Design tokens scoped to :host — each component that imports the stylesheet gets its own token scope, matching Lit's shadow DOM encapsulation model

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Performance plumbing and design tokens in place
Ready for Plan 02 (subsequent frontend work can import designTokens)
Library store subscribers will automatically benefit from coalesced notifications
