The platformer starter reused the sprite cached by each spritesheet frame name for every matching terrain tile. Later placements moved the same nodes across the map, leaving most of the floor invisible. Create a distinct Sprite for every tile from the public texture and frame APIs, while retaining the existing merged physics bodies.

The focused regression failed with two floor nodes instead of sixty before the fix. All five platformer consumer tests now pass, including floor and raised-platform positions, tile dimensions and existing fixed-step jump behavior.

Stack base: sweep/v020-integration-lifecycle at 34662c81a66800aa0f7919d6d774cc87f0304116. Head: d195528c3e265e7d23ba2198813a6324a28c6476. This PR changes only the platformer scene and its regression test.

Validation: pnpm exec vitest run --project=exojs test/templates/platformer-consumer.test.ts. Generated starter install/build passed. Three bounded production-dist trials show actual horizontal movement, confirmed by direct-canvas and compositor captures. Earlier screenshot-only runs intermittently captured old or pose-only player images; that timing/capture anomaly remains unresolved, and DOM readback may affect timing. The earlier heuristic PASS is not counted as movement proof. Exact-head CI and the combined candidate status are recorded below.

• Exact head d195528c3e265e7d23ba2198813a6324a28c6476: CI run 38845398966, completed / success.

Combined stack: d195528c3e265e7d23ba2198813a6324a28c6476, tree c64f60bfd5d5e5a4210281ff6b3bfe120482fac1. Integration qualification: CANDIDATE_QUALIFIED. These combined results belong to that SHA, not to each earlier stack head.

Combined mandatory evidence: 18/18 final CI jobs; normal local pre-push gates and seven selected lanes; Firefox WebGL2; 162 parity checks; 108 full-example smoke passes with one intentionally WebGPU-only skip; all six generated starter builds; 13 hashed candidate tarballs and strict public-package consumers. Existing package versions remain 0.19.1; artifacts are unpublished candidate builds.

Local Firefox WebGPU executed and failed: Core 3 failures, media 4 failures, isolated row timeout. Mesh and video-copy failures also reproduce on the verified base; two full-suite Core timeouts do not reproduce in fresh named runs. CI Firefox WebGPU is separately UNSUPPORTED_HOST. These informational outcomes remain failures/unsupported, not passes. Tiled 1.12.2 authentic exports remain unverified; strict NodeNext declarations remain unsupported.

Firefox WebGPU follows the existing informational policy. An unsupported host is not an executed rendering pass. This branch is unmerged; no release or package publication is implied.
