Create a 3-lane endless runner as ONE self-contained HTML file. Genre: auto-run forward; dodge obstacles in left/center/right lanes. Lanes: 3 vertical lanes; player snaps to lane centers. Controls: left/right or A/D to change lane; down or swipe down to slide under (optional). Obstacles: barriers, gaps, low/high types requiring jump or slide if implemented. Jump (optional): short arc to clear low obstacles — keep readable on mobile. Score: distance or time survived; speed increases gradually. Collectibles: coins optional for bonus points. Collision: hit obstacle = game over; brief feedback. Camera: side or behind angle — obstacles approach from ahead/right scroll. Touch: lane buttons or swipe left/right. Title + game over screens; restart without reload. First 3 seconds easier spawn rate. Obstacle patterns must be dodgeable — no unavoidable combos. 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.
