967e81d33f docs(prd): learner-first mobile app PRD and interactive prototypes (#916)
* docs(prd): add learner-first mobile app PRD and interactive prototypes

Draft the ClassroomIO iOS/Android companion as a learner-first product
(attention home, compliance wallet, offline content, push on top of
prd/notification-system) with clickable HTML prototypes as the UX source
of truth.

* style(prd): quiet mobile app prototype colours to match @cio/ui

Replace filled red/orange/green surfaces with the dashboard Badge and Alert recipes: 10% tint chips, card-background alerts, and default rows. Keep destructive fills only for actual destroy actions.

/*
* app-theme.css — shared theme for the ClassroomIO mobile-app prototypes.
*
* Tokens mirror packages/ui/src/index.css (shadcn-svelte) exactly: OKLCH
* palette, Geist, --radius: 0.625rem, and the Button / Badge / Item / Progress
* recipes from @cio/ui. Dark mode uses the same `.dark` class as the app.
*
* On top of those tokens this file adds the mobile shell primitives the
* dashboard has no equivalent for: a 390x844 device frame, status bar,
* nav bar, bottom tab bar, list rows, bottom sheets, banners and toasts.
*
* Semantic colour follows @cio/ui, not filled surfaces:
* Badge — rounded-full, 10% tint + coloured text (learners-table)
* Alert — destructive is card + red text; warning/info use amber-50 / sky-50
* Rows — default card; status lives on a chip, never a painted row
