Description

Closes #1707. All 28 hand-written WIDGETS tools (the first fifteen: jtag-verdict, race-the-bee, t27-vs-nvfp4, t27-cell, build-receipt, uart-bucket, test-touch, lut-depth, lut-explain, gf16-calc, resource-bars, pin-map, fsm-sketch, cost-curves, fits-on; then synth-smells, vcd-wrapped, stat-card, lut-treemap, fasm-skyline, bit-diff, bit-autopsy, idcode, slack-waterfall, test-waves, placement-map, gatle, t27c-stages) move from hand-written tool.js to pages written in .t27 and built to wasm, driven by one shared host.js. Epic Trinity-S-AI-DNA/t27#10937.

Read by the model

This PR migrates 28 widget tools from hand-written tool.js files to .t27 source compiled to widget.wasm, all driven by a single shared host.js (260 lines replacing ~9k lines of tool JS). The compiler was rebuilt to support module-level vars in specs, and play pages were regenerated.

Worth a look

• apps/website/public/widgets/host.js:1–260 — New shared host replaces 28 tool-specific JS files. Any bug here affects all 28 tools at once (canvas setup, data loading via W_DATA_FILE(S), event wiring, error handling). Verify it correctly handles every tool's unique entry points and data shapes.

• apps/website/public/widgets/*/index.html — Each tool's page now loads ../host.js instead of ./tool.js. The diff shows only script-tag changes, but if any tool relied on inline scripts or load-order quirks in its old tool.js, those are gone. Spot-check a few pages (e.g., fsm-sketch, bit-diff) for missing initialization.

• apps/website/public/t27/t27_compiler.wasm — Rebuilt compiler (731k → 794k bytes) to accept module-level vars in specs. This binary is not diffable; a regression here would break all 40 regenerated play pages and the 28 widget specs. The CI failure on first push (check:play staleness) suggests the regen step is sensitive.

• apps/website/scripts/widget-pages-from-spec.mjs — Generator now treats a folder with widget.wasm and no tool.js as "native." If the detection logic misclassifies a tool (e.g., a future tool with both files, or a stale tool.js), it will emit the wrong page. The --check passed, but the logic is new.

• apps/website/public/widgets/lut-depth/, lut-explain/, lut-treemap/, pin-map/ — These four tools show .t27 and index.html as modified but with +0 -0 line changes, yet their tool.js is removed and widget.wasm added. The diff doesn't show the .t27 content changes (if any). Confirm the specs for these tools are actually native now and not accidentally left as empty/stub files.
