Create a classic Snake game as ONE self-contained HTML file. Genre: grid-based snake eats food, grows longer, dies on wall or self. Board: ~20×15 grid (or similar); visible grid lines optional. Movement: 4-direction on a timer tick (not real-time free move); queue next turn input. Food: spawn on empty cell; eating increments score and length. Speed: increases every 5 foods or fixed ramp. Wrap walls (optional) OR solid walls — pick one and document on HUD. Keyboard: arrows/WASD; touch: swipe or 4-button pad. HUD: score, high score, length. Game over on collision; R or tap to restart. Start overlay: press key to begin. Distinct head color; body follows tail. No diagonal movement. Ensure food never spawns inside snake. Output: full HTML only (<!DOCTYPE html> ... </html>), no markdown fences. Stack: inline CSS + inline JavaScript only. No npm, no build step, no local file deps. Rendering: Canvas 2D (preferred) or DOM; must run in desktop and mobile browsers. Controls — keyboard: document in a title/HUD overlay; R to restart. Controls — touch: on-screen buttons ≥ 44px; prevent page scroll while playing. Flow: title → play → win or lose → restart without reloading the tab. HUD: score and clear objective; high-contrast text on small screens. Do not use alert() for main UI; use canvas/DOM overlays. Do not use onclick= inline handlers; use addEventListener. Do not access parent/top window or iframe sandbox escape. Do not depend on external URLs for core gameplay assets. Optional Web Audio after first user gesture; fail silently if blocked. Smoke-test: first 30 seconds are playable, not menu-only. Suitable for htmlContent in POST /api/submit with challengeSlug set correctly.
