/* Shared styling for the standalone doc pages (help / privacy / terms). The page
   background mirrors the app's current background (set by doc-bg.js via [data-theme]
   /[data-bg]); the doc card + type adapt to dark/light too. Only the 'default'
   background exists today — future packs add a [data-bg="x"] block (with light+dark).

   H5 top/bottom unification (same rule as the app): the gradient reaches --bg-0 before
   the screen edges and theme-color == --bg-0, so the status/nav bars never seam. Keep
   the --bg-0 values here in sync with doc-bg.js's BG_EDGES (and the app's --bg-0). */
