[Vatsal2005]

What and why

Space/K and gamepad A/Cross now jump with a 52px minimum tap rise, about 96px held rise, 0.1s coyote time and a 0.12s input buffer. The supplied landing drawing plays on contact; drops of at least two body heights select the four-frame hard landing at 12fps. Sprites are never scaled for squash. F2 keeps the measured apex height visible after landing.

Issue

Closes #28

Base: feature/27-walk-and-run. Human merges bottom up; retarget the next PR to main and merge origin/main into every open branch, never rebase.

Acceptance criteria

• Variable tap/hold height, approximately 52px and 96px
• 0.1s coyote time and 0.12s jump buffer
• Landing pose and four-frame hard landing are selected from the supplied atlas

Verification

• Node 22: npm run typecheck, npm test (66 tests), npm run build; includes main integration at e8577ab
• py -3.13 scripts/check_docs.py
• git diff --cached --check
• Tests simulate complete tap/held/intermediate arcs, late coyote rejection, buffer expiry, no repeated jump from holding, and normal/hard landing selection
• Browser: Space tap measured 51.2px, K hold measured 96.1px, landed back on Garden floor without drift or console errors
• Every Creek deck, coyote and buffering in the route: complete after [M1-S3] Walk up hills and slide down steep slopes #29/[M1-S4] Drop through one-way platforms and climb ladders #30 provide slopes, one-way platforms and ladders
• Physical gamepad and Vercel preview: Vatsal2005 needs project access to create Vercel deployments
