Dispose scene resources before renderer allocation records are cleared and
release the bloom high-pass material. Avoid unused bloom depth buffers and
the final screen pass swap, keeping the same visual output and quality.
Batch sign-stage layout reads before applying existing masks.
Validated approved assets, types, client and SSR builds, prerendered content,
artifacts and transfer budgets. Checked 32 matching transition renders,
66 browser interactions and repeated quality-change resource cleanup.
