/* ==========================================================================
   Pixel Academy — Student app
   One shared product identity for the three authenticated student pages:
   account (profile), purchased lessons, and codes / wallet.

   Depends on pixel-v2.css (tokens, typography), pixel-public.css (shell
   primitives: buttons, drawer, header geometry, theme toggle, atmosphere)
   and pixel-public-pages.css (state panels, skeletons, notes). It never
   modifies any of them and never redefines the theme system — every adaptive
   value below is derived from tokens that already flip with html[data-theme].

   This is a product surface, not a marketing page: compact navigation, one
   card system, one state system, one form system, one dialog system.
   Prefix: pxs-
