Each web demo builds with its base path under /ai-coding-workflow-labs/,
a single deploy workflow assembles them with a root index, and the
per-directory workflows from the standalone repos are removed.
Tile pop and merge @keyframes were setting transform: scale() which
overrode transform: translate() used for tile positioning, causing
tiles to jump to (0,0) during animation. Fix by using individual CSS
properties: translate for positioning, scale in keyframes.
- ScoreBoard: wrap floats mutation in untrack() to prevent $effect
from re-triggering when it reads+writes floats in same cycle
- App: split bestScore effect and use untrack() to prevent read/write
loop on bestScore within the same $effect
- Add box-shadow glow effect on tiles with value 128+
- Dynamic font sizing already implemented in Epic 4 responsive work (Story 5.2 = no-op)
- Set Vite base path to /try-bmad/ for GitHub Pages
- Add GitHub Actions workflow for automated deploy on push to main
- Production bundle 22.4KB gzipped (under 50KB target)
Tiles now slide smoothly to new positions with 100ms CSS transitions.
New tile-tracker.js module manages tile identity across moves, enabling
Svelte to reuse DOM nodes for CSS transition animation. Input queuing
prevents moves during animation. Supports prefers-reduced-motion.
59 tests passing (10 new tile-tracker tests).
All Story 2.3 ACs already satisfied by Stories 1.2, 1.6, and 2.2.
Keep-playing mode works: flag persists across sessions, win overlay
suppressed, game over still triggers. Epic 2 done.
Game state saved after every move, restored on page load. Best score
persisted separately. New Game clears game state but preserves best
score. Schema validation prevents crashes from corrupted localStorage.
49 tests passing (11 new storage tests).
Epic 1 code review passed with 0 patches needed — all 6 stories
marked done. 6 deferred items logged for Epics 2-5. Created story
2-1-best-score-tracking as ready-for-dev to begin Epic 2.
ScoreBoard shows current/best score. Keyboard arrow keys control
gameplay via input-handler module. GameMessage overlay shows win/game
over states with Keep Going, Try Again, and New Game actions.
Grid.svelte renders 4x4 board with empty cell placeholders.
Tile.svelte renders colored numbered tiles with absolute positioning
and ARIA roles. App.svelte owns game state via Svelte 5 $state rune.
Pure JS game engine with initGame, move, canMove, isGameOver.
Implements leading-edge merge order, once-per-move rule, 90/10 tile
spawning, win detection (2048), and immutable state updates.
Initialize project with Svelte 5, Vite 8, Tailwind CSS v4, and Vitest.
Set up folder structure (src/lib, src/components, public/fonts),
constants module with game values and 12-tier tile colors, Clear Sans
font, and page background styling.
