/*
 * Apollo UI — card styles type-1 … type-6 + the full-viewport overlay.
 *
 * TOKENS
 * :root belongs to core.js. Nothing here declares a global design token.
 * Every custom property below is component-scoped (--aui-*), which is the
 * pattern the design system explicitly allows and the reason a new :root entry
 * is treated as a defect.
 *
 * ONE MARKUP, SIX LOOKS
 * .aui-card is identical for all six types. The differences are:
 *   --aui-ratio        set inline per type (2/3, 16/9, 1/1, auto)
 *   .aui-media-*       poster | landscape | square | circle | none
 *   .aui-layout-*      stack | row | bare
 * That is the whole point — a surface changes look without forking markup.

 * This is apollo-ui's own overlay, used ONLY for surfaces with no delegate.

 *
 * `100dvh` matters: on mobile Safari `100vh` is the UNCOLLAPSED viewport, so a
 * "full viewport" panel is taller than the screen and the close button in the
 * top-right sits under the URL bar — unreachable, which is the one control the
 * user must always be able to hit.
