HEDGE 2 (rules-level): plain `gr.Blocks` + full-bleed `gr.HTML` wrapping the
IDENTICAL built bundle in a same-origin iframe served via the file route.
Activate by setting `app_file: app_blocks.py` in README.md — zero bundle changes.

Spike checks (§9.0 path C): WebGPU + module Worker + IndexedDB inside the
nested iframe; sizing; pointer/keyboard not captured by Gradio.
