/*
 * Material 3 for the web, hand-rolled.
 *
 * Colour roles are the exact values from composeApp/.../theme/Color.kt, so the PWA and the
 * Android app render the same theme. The type scale, shape scale, elevation levels and state
 * layers follow the M3 specs. (@material/web is no longer actively developed, and a web
 * component library would cost more bundle than these tokens do.)
 *
 * Layout uses logical properties throughout, so Arabic RTL needs no overrides.
