Sunwake now gives each run more to master and a reason to return to the same course. Four continuous terrain profiles, thermal updrafts, one-hit shields, spark magnets, three-ring sky chains, and perfect landings add variety and reward timing. Burst recharge and sunlight use are balanced around the new pickups.

Players can race a saved best-run ghost, share versioned course links, and revisit their last twelve flights. Debriefs show the flight path and useful skill metrics; four new challenges extend progression. Existing records, light, skiffs, and completed challenges are preserved. Ghost storage is bounded and still works in memory when browser storage is blocked.

Contextual coaching, independent keyboard/touch holds, clearer pickup status, larger mobile controls, and compact landscape fullscreen results improve playability. Violet islands and blue aurora add regional character; terrain caching and fewer idle React updates reduce rendering work.

Validation:

• Exact repository gate: conformance, frozen pnpm install, lint, build, and subpath-safe output.
• Expanded deterministic engine checks, four-minute practice simulation, and 22 progress/replay/input tests.
• Twelve Chromium browser scenarios, including 320/390 px touch play, landscape fullscreen, ghost accuracy, shared courses, history, migration, purchases, and clipboard/storage fallbacks.
• Visual review of desktop, portrait, landscape, and both new region effects; no console errors or horizontal overflow.

All changes are confined to projects/sunwake-a6f3/.
