Playtest fixes (two reports, both bugs):
- Bad ground no longer instantly crashes: holes and obstacles only
put you down above surfaceCrashSpeed; below that you bog to a crawl
that is capped under the crash speed, always escapable
- Steep ramps (45°) no longer crash: launch lifts the bike clear of
the lip, pitch is clamped to pitchMax, and landing angle is clamped
to landGroundAngleMax so straddled cliff edges don't count as
rideable surfaces
- Harness now drives every ramp at seven speeds; no crashes allowed
Wave 5 polish:
- Scenery: infield and apron shrub rows (bush, apronBush, tuft)
transcribed from NES track maps
- Ramps given readable silhouette (packed-earth hatch, dark stroke,
lit crest, sheer-face cut)
- Gaps show infield through lane; lane dividers and cool-zone
chevrons fixed for alternating-lane contrast
- Snow and night themes retinted for visibility
- iconFrame 91 already painted
Tooling:
- Map reader masks ramp columns to avoid false mud/cool-zone detection
- All 10 track qualifyMs retuned from playtest measurements
