/* ============================================================
   .glass-panel — canonical "content card" utility for body

   class form so pages can apply it without importing the
   <GlassSurface> primitive for every flat container. Added by
   glass-body-panels PR after PR #96 left admin/settings/dashboard
   body cards on solid --bg-secondary.

   Composition matches <GlassSurface tint="mid" rim="subtle"
   elevation="ambient" blur="mid">. Always pair with rounded-*
   from Tailwind (the class itself doesn't set border-radius
   because consumers vary between rounded-xl and rounded-2xl).
   ============================================================ */
/* IMPORTANT — composing rim + elevation tokens correctly.
   The --rim-light-outer / --rim-light-inner / --elevation-* tokens are
   COMPLETE box-shadow declarations (each contains offset/spread/color or
   the `inset` keyword), not raw color values. They are designed to be
   *chained into a single box-shadow*, exactly the way <GlassSurface>'s
   `boxShadow: shadowParts.join(', ')` composes them. Do NOT use
   `border: 1px solid var(--rim-light-outer)` — that parses
   `border-width` from the first token of the shadow string ("0"), which
   yields a 0px border. And do NOT wrap --rim-light-inner in another
   `inset 0 1px 0` prefix — the token already contains its own `inset`
   keyword, so wrapping produces invalid syntax that the browser drops
   the entire box-shadow declaration for. PR #98 had both mistakes,
   which is why the panels in PR #97/#98 had neither visible border nor
   drop shadow despite the backdrop-filter being correct.

   Backdrop-filter quirks with Next.js 16's Lightning CSS (also relevant):
   1) `backdrop-filter: blur(var(--X)) saturate(var(--Y))` is silently
      stripped (var() inside function args breaks the optimizer). Use
      LITERAL values here. Tokens stay in :root for the <GlassSurface>
      JSX primitive which sets backdropFilter via inline style.
   2) Writing both `backdrop-filter` AND `-webkit-backdrop-filter` with
      identical values triggers Lightning CSS's buggy de-dup; it keeps
      only the `-webkit-` form which modern browsers ignore. Write only
      the unprefixed form; Lightning CSS's autoprefixer adds the prefix
      per browserslist (ios_saf <18 still needs it). */
