Embed KiCad's gerbview WASM in the graphics-to-WebGL blog post as a
click-to-load demo that opens the tiny_tapeout board entirely in-browser.
- GerberDemo.astro: lazy iframe embed + cross-origin-isolation reload guard
+ WebGL2/SharedArrayBuffer feature-detect with a poster fallback
- public/gerber-demo/{index.html,boot.js}: self-contained gerbview boot
harness (config seed, MEMFS board preload, argv auto-open)
- board/ tiny_tapeout layers + poster.png committed; wasm/ glue JS committed
(served same-origin — pthread worker can't be cross-origin), while
gerbview.wasm + kicad-resources.bin are git-ignored and served from
Cloudflare R2 (assets.pcbjam.com)
- COOP/COEP require-corp scoped to the post + /gerber-demo routes
(dev: astro.config.mjs + middleware.ts; prod: vercel.json)
- post converted to MDX (@astrojs/mdx) so it can embed the component
- scripts/: sync-demo-wasm.sh, r2-deploy.sh, r2-cors.json
