Restructure Tetris Attack Stage Clear from "clear all target panels" to a
multi-stage round system with a sliding boundary line.
Gameplay changes:
- Each character now has 5 stages instead of a single match
- A CLEAR line appears after a set number of rows rise, then rides the
stack upward; the objective is to clear everything above it
- Clearing a stage advances to the next: same board, faster speed, fresh line
- Stage progress is saved to localStorage; characters unlock sequentially
- Added a stage select screen with progress squares per character
Logic changes:
- Replaced `targetsTotal` with `clearLine` tracking and `countAboveLine`
- Added `advanceStage()` to resume play on the same stack one speed level higher
- Win condition now checks `countAboveLine() === 0` instead of target count
- Removed `target` flag from panels; panels below the line are irrelevant
- Continuous speed ramp via fractional `speed` per stage
UI changes:
- Clear line drawn as a pulsing bar with "◀ CLEAR" label outside the board
- "CLEAR LINE!" announcement on appearance, "STAGE N CLEAR!" banner on win
- HUD shows stage number instead of panel count
- Game over offers "Retry Stage", "Stage Select", or "Menu"
Asset changes:
- Backgrounds renamed to `background-{hero}-r{stage}.png` (5 per character)
- Lazy-load backgrounds per round instead of preloading all 30 images
- Updated tetrisattack.json with `stagesPerRound`, `stageSpeedStep`, and
per-character `clearLineRows`
Tests:
- Rewrote stage clear soak tests for the new mechanic
- Added stage round progression, speed ramp, and board preservation tests
Implement the full Tetris Attack clone with three game modes:
- Endless: clear panels as the stack rises, speed increases with levels
- Stage Clear: defeat 6 character opponents (Beth, Jerry, Michael, Steve, Victor, Klaxon) in sequence
- Puzzle: solve 24 pre-vetted puzzles within move limits
Core engine (src/games/tetrisattack/TetrisAttackLogic.js) is a pure, deterministic
state machine with match detection, chain propagation, gravity, and scoring tables
matching the SNES original. Includes a headless verifier (verifyTetrisAttack.js)
testing match detection, chains, gravity invariants, top-out, puzzle solvability,
and seeded determinism.
Art is fully optional via drop-in spritesheets (spec: sprites.md); procedural
fallbacks draw 16-bit-style panel icons with distinct shapes for colorblind access.
Puzzle bank generated by genTetrisAttackPuzzles.js and verified as solvable within
optimal move counts.
Shared nintendo soundtrack reused via soundtrack overrides.
Introduce a unit unlock system that progressively grants access to new
unit types as the player advances through the campaign. Each mission
specifies which units each army can build, starting with basic units
and unlocking MD Tanks, Rockets, Anti-Air, Missiles, Lander, Cruiser,
and eventually the full armory.

pathfinding, economy, capture, fog, CO powers, soak tests)
- New assets: terrain/building sheets, adventure music tracks,
game icon frame 86
- Refactor SpireClimb and SWDBG to use the shared soundtrack service
- VictoryCamDirector: cinematic post-race camera system with shuffled
shot types (chase, orbit, front, trackside) and hard-cut transitions;
player can press ENTER to skip.
- Engine audio: per-racer engine hum (heavy/fast/medium) with pitch
tracking based on kart speed; engine-start sound at green light.
- Star power loop sound that stops when star expires.
- Positional audio: AI kart sounds (spin, hit, flatten) scale volume
with distance from player.
- Enhanced event sounds: item-use, boost, EMP, squash, bump, coin,
star now play appropriate SFX.
- Player kart autopiloted after finishing for victory-lap vignette;
race phase waits for entire field (up to 90s safety cap).
- EMP now emits target list for per-target shrink sounds; squash
collision emits event.
- Animated race results screen with staggered row reveals.
- Animated cup standings with running point counter and position
arrows; tweens rows to new ranks.

- Add Coinage (1 shield → 1 gold) and Public Works (2 shields → 1 food)
special build options for cities, with remainder carry logic in shieldBox
- Update AI to fall back to producing gold or food instead of stockpiling
redundant defenders when nothing else is available
- Fix mid-build detection to check build.type before comparing shield progress
- Add City Screen UI for special builds: display gain per turn, color-coded
rows, and tooltips
- Only apply class-switch penalty when switching between unit/building
production types
- Add verification tests for coinage payout, public works remainder carry,
and AI special build fallback
feat(superkart): fix player kart scale + add missing backdrop images

to prevent tall features from being overwritten by lower-sum neighbors
- Stop panTween on pointer down to avoid conflict with manual dragging
Allow each opponent to declare their own 2-3 starting technologies in
opponents.json, independent of their civ trait. During game creation,
personal and trait-based starting techs are unioned (deduped) so
pioneering leaders with overlapping lists don't double-grant.
- Add optional setup screen background image (civilization-setup-bg)
- Update leader detail panel description to list personal starting techs
- Deduplicate trait + personal techs via Set in CivilizationLogic
- Add validation for startingTechs arrays, tech existence, 2-3 total count,

- Nudge unit sprite position 5px down for better tile alignment
When a city cannot complete a build (e.g., size < 2 for settlers),
shields were accumulating past the build cost, showing confusing
values like "60/40 shields" or negative turn counts.
- Cap shieldBox at buildCost each turn in processCity
- Clamp displayed shields to min(shieldBox, cost) in city screen
- Add tests verifying shield capping and stalled build completion
- Capture attacker/defender snapshot (id, civ, type, start position) in
combat events so the UI can reconstruct them after resolution

- Update game icons to include Star Control icon (frame 82)
- Replace time-based splitAt/splitDone with screen-space Y zones (SPLIT_ZONE_1
at top third, SPLIT_ZONE_2 at halfway) for more predictable MIRV behavior
- Add MIRV_RESPLIT_WAVE (wave 8): from wave 8 onward, MIRV buses split twice
instead of once, creating more late-game pressure
- Lower early-game difficulty: MIRV starts at wave 3 (was 6), reduced base
chance (0.05 vs 0.15), increased growth rate, lowered max (0.4 vs 0.5)
- MIRV trunk continues flying toward its target after each split
- Updated verification tests for split-zone geometry and new missile fields
- Cleaned up obsolete splitAt/splitDone fields across test fixtures

- Add Force track shift SFX (light/dark variations) with randomized playback
- Update verification tests for new card behaviors
Add a "Spells" button during adventure room windows allowing the human
to cast hand spells targeting the hero currently mid-crawl (not just
entrance-queued heroes). The adventure modal stays open across the cast,
narrates spell effects as banners, and correctly resumes the walk
afterward without skipping rooms.
Key changes:
- New `adventurePause` walk type and `ADV_RESUME_MARKERS` to mark the
boundary between a cast's own effects and resumed walk events
- `findHero` now locates heroes in `adv.walking.hero`
- `showPickModal`/`showReactModal` accept custom callbacks to stay
inside the adventure modal session
- `driveAdventureWindowDecision` routes window/react decisions to the
modal UI instead of closing it
- AI window/react turns are computed and revealed via a "has cast:"
overlay before applying
- `applyAdventureWindowChoice` applies choices directly to the engine,
splits events into narration vs resumed walk, and plays banners
- New event types (`roomBoosted`, `heroHurt`, `heroHealed`, `heroFeared`,
`heroTeleportMarked`, `heroesBlocked`, `soulBurned`, `handReset`)
render as banners in the narration pipeline
- Two new verification tests for mid-walk targeting and fearHero safety
- SWDBG: add animated buy sequence with funding arcs, center-screen reveal,
and face-down stow to discard/deck
- SWDBG: introduce stable row slot tracking so bought/lost cards don't shift
neighbors; add ghost cards for pending animations
- SWDBG: add end-of-turn discard animations preserving old-hand positions;
emit endTurnDiscard events from logic
- SWDBG: add deep-dive Buy/Attack buttons for actionable cards; refactor
dealCardAnimated with startAs/flipTo/keepAlive support
- SWDBG: add drawArcArrow/drawArcArrows for converging attack visuals on
bounty kills and base attacks
- Dungeon Boss: add mid-walk advRoom casting window after room events,
letting players react to damage/kills during hero crawl
- Dungeon Boss: track walking hero in publicView and entranceHeroesOf so
spells and AI heuristics can target mid-crawl heroes

pending bait heroes stay in town with fly-in tokens; pending draw cards
show card backs until animations land
- Dungeon Boss: keep heroes in battle zone after roomHit/pass instead of
returning them immediately
- Update images, registry (defaultPlayfield), and verifier (advRoomCasts)
Implement two complete card games with full rule engines, AI opponents
(5 skill levels), procedural rendering, and drop-in art support.
Dungeon Boss: Boss Monster-style dungeon building game for 2-4 players.
Players build dungeons of rooms and spells to lure and defeat heroes,
harvesting souls to win. Includes 8 bosses, 31 room cards, 16 spells,
and 41 heroes with class-based baiting mechanics.
Star Wars Deckbuilder: 2-player deckbuilding game. Players build decks
from faction and neutral cards, purchase from the galaxy row, bounty hunt
enemy units, and attack bases. First to destroy 3 enemy bases wins.
