   builder built v1

   • Chai-cup scooter auto-rides a rain-soaked street; swerve with ←/→ or A/D (and the touch buttons) to dodge potholes (dark craters) and puddles (blue splashy ellipses), either ends the run.
   • Scoring: +1 per second survived, +10 per samosa grabbed (with a steam-sparkle burst, chime and floating "+10 samosa!" text).
   • speed ramps with run time, which raises both obstacle fall speed and spawn frequency (shorter spawnIn), plus rain-streak intensity.

8. 🧪

   playtester reproduced it headlessly: BUG 1: scooter stays on the road, not the sidewalk

   Saved as v1/repro-1.json, replayed by every later playtest.

   
9. 🩹

   builder shipped hotfix v2: scooter rides onto the sidewalk and hazards can appear off-road

   • Added a roadClampX(x, halfWidth) helper that keeps any object's edges inside the road ([view.w*0.08, view.w*0.92], 14px buffer); the scooter, potholes/puddles and samosas all spawn/move through it now.
   • Holding a direction into the shoulder now stops the scooter well inside the road (playerX ≈114 at 960px wide, vs the old 23) instead of letting it park on the sidewalk.
