Rebuild IHFK as a Phaser 4 kiosk destruction game

[Lee-WonJun]

What changed

• Rebuilt IHFK as a static Phaser 4.1 game with Language → Title → Intro → FastFood → Street → Factory → Result → Endless flow.
• Added ten locales, desktop/mobile landscape input, kiosk-style menu/HUD/result UI, fast fist/bat/chainsaw/shotgun combat, falling kiosk physics, factory hit/destruction feedback, synthesized MIDI-rock audio, share card and fallbacks.
• Replaced prototype visuals with intentionally C-grade raster backgrounds, kiosk damage stages, full-character weapon animations and pixel pickups.
• Preserved the original implementation under legacy/.
• Added master/spec documentation, QA pages, static asset validation, browser tests and exact 1080×640 evidence captures.

Why

The original jam game mixed all behavior into a small legacy runtime and did not support the agreed three-stage campaign, mobile controls, localization, weapons, result sharing or endless mode. This refactor separates scenes, entities, services, input, localization and UI while preserving the fast, rough original tone.

Validation

• npm run check passes: 24 modules, 40 runtime assets, 10 locales × 25 keys, 11 SPEC documents, raster/palette/alpha gates, and five exact 1080×640 captures.
• Browser suite: 29 passed, 0 failed, console errors 0.
• Full 50-kiosk/5,000-HP Pages-subpath autoplay campaign reaches Result.
• Forced-touch 30-kiosk stress holds 60 FPS in the current desktop browser environment.

Remaining release evidence

Physical Android/iOS fullscreen, orientation, native share and final listening/human timing checks remain documented P3 evidence gates in docs/evidence/DEVICE_QA_TEMPLATE.md.
