/* bdils.com theme skin: FROST (glass over colour). Scope html[data-theme="frost"]. Apollo.
   Visual contract: postmodern-directions.html direction 05 and comp-d5-hero.png / comp-d5-phone.png. Palette: mist, mint, peach, lilac field; cobalt action; ink text.
   Panes: white 55-82%, blur 22px + saturate 1.6, 1.5px white rim, soft blue-violet shadow. Text only ever sits on panes at >= 55% white over the pale field, so AA holds on every pane (measured, see a11y report).
   prefers-reduced-transparency drops all blur to opaque #f4f6ff. Slow field drift is a Zephyrus/engine duty, not CSS, and is off before the first gesture. */
