Inside t27c: watch a compiler read your code, stage by stage

Edit a small t27 spec and see what the real t27c compiler, running as WebAssembly in your tab, makes of it: tokens, tree, type check, HIR and code in seven languages.

Where the numbers come from

public/t27/t27_compiler.wasm (731,581 bytes, sha256 bb39b9a5ca412a26...): the t27c compiler built for the browser from gHashTag/t27 bindings/wasm-explorer, vendored in trinity commit a41600ad7
Every stage is computed in your tab by that file's t27_analyze export on the text in the box; nothing on the page is precomputed and nothing is sent
node 22 scripts/widget-data/t27c-stages.mjs: runs the same wasm on this spec's examples, checks the K_EXAMPLE_ numbers and writes examples.json, from which scripts/widget-data/t27c-stages-card.py draws card.png
