Changes for this platform: Switched the renderer from Forward+ to Compatibility (gl_compatibility, GL Compatibility feature tag) so it runs in browsers; exported with Godot 4.6.3 as a single-threaded web build (thread_support=false) using the platform's standard web export preset; the engine runtime is served from the platform's shared /engine/godot/4.6.3/ instead of being bundled; replaced the default HTML shell with a launcher that shows a loading backdrop and calls ArcadeSDK.ready(). Fixed the background TextureRect, which was pinned at a fixed 1280x720 top-left offset, to anchor to the full rect with stretch_mode=KEEP_ASPECT_COVERED so it covers the viewport at any aspect ratio (incl. 390x844 mobile) instead of leaving black gaps. Scaled the board container down (board_scale=0.6 on top of the kit's own 68px tile offset) and recomputed the centering math so the full 8x8 grid fits on a 390px-wide phone viewport with margin. Added, in scripts/main.gd: a title/playing/game-over state machine; a score counter (+10 per matched gem, multiplied by cascade/combo depth) shown on a HUD and reported via a guarded SDK.score(n); a 20-swap move budget (decremented only on swaps that produce a match) shown on the HUD, ending the run via a guarded SDK.gameOver({score, won:false}) and SDK.submitScore(n) when it reaches zero; a title screen and a game-over overlay (both built at runtime from Control/Label/Button nodes, no .tscn edits) with a Tap-to-Play / Tap-to-Restart button that also responds to keyboard Enter/Space via focus; a restart path that frees the board and fully resets score/moves/state; and best-score persistence through the guarded ArcadeSDK.storage.get/set pattern (key "match3-best-score"), shown as "Best: n" on both the HUD and the title/game-over screens. All of this mirrors the exact JavaScriptBridge guard style used in the City Builder port's scripts/builder.gd. Core match-3 gameplay (swap/match/cascade/collapse/refill logic, sprites, sounds, cursors) is unchanged from Kenney's kit.
