Free-form radio adds a 5th demo slot. When selected, a vault bar appears under the controls: enter a password, "unlock" derives a per-device vault and decrypts (or creates fresh). Edits in the editor auto-save 350ms after typing stops. Reload + same password restores the code. Same Web Crypto stack as /repl/ (PBKDF2 + AES-GCM, vault id = SHA-256(password || device-salt)). Layout: one shared vertical scroller — code pane and output pane both grow with content, the body scrolls. No more independent in-pane scrollers fighting the page. Home page split into "Demo" and "REPL" sections with their own CTAs.

|
|
# ═══════════════════════════════════════════════════════════════════
|
|
#
|
|
# Builds:
|
|
# python/ — Pyodide loader + lumbda.py (CPython-in-WASM)
|
|
# c/ — Emscripten build of c/ (tree-walker + bytecode VM, no JIT)
|
|
# asm/ — Hand-written WAT compiled to wasm (parallel "asm" tier)
|
|
# app/ — Single-page app shell (HTML + CodeMirror + JS glue)
|
|
#
|
|
# Targets:
|
|
# make build all three tiers + SPA bundle in dist/
|
|
# make test unit (node) + integration (node, cross-tier diff)
|
|
# make test-fn functional (playwright headless browser)
|
|
# make serve local dev server on :8080
