isometric demo

Signed in as __USERNAME__. Odin + raylib compiled to WebAssembly via emscripten. QWE/A D/ZSC walk the 8 compass directions (numpad-style) — one tile per walk cycle, stops snap to tile boundaries. Speed is live and directional: it scales with how closely you point along the travel direction (full speed dead ahead, 100% floor pointing away), 100%–180% — the walk cycle prunes its least-moving frames first (endpoints and no-consecutive always kept). Numpad +/− steps the requested speed; gamepad left stick magnitude sets it in real time (press a button first to activate). Current speed shown top-left.
