Clean, dependency-light front page. Only three things ship here:
- index.html — two-button landing: Mobile -> mobile.html, Desktop -> pm_e-2.html
- mobile.html — touch-first PWA (+ mobile-sessions.html practice journal)
- pm_e-2.html — engraved-notation editor
build.sh/deploy.sh trimmed to just these; deploy mirrors dist/ to the web root
with rsync --delete. README/CLAUDE.md rewritten for the slim scope.
The full project (PM_E-1 editor, embeddable widget, all hardware form-factor
pages, Pico firmware editions, the Rust port, and the KiCad/SPICE hardware
design) is preserved on the `concepts` branch.
