Installable, offline-first PWAs — each shipped as a single static file, no framework, no build.
Undosus
A small family of free, installable, account-free musical-training apps — one discipline per app, one shared design language. Each is a single static file: no framework, no build, zero JS dependencies, bilingual FR/EN, dark-first, offline-capable. undosus.com is the landing page that ties the suite together.
