/* ============================================================================
   PPX "Lucky" — the floating deck.
   Standalone stylesheet: loaded INSTEAD of styles.css when the Lucky theme is
   active. Palette LOCKED to exactly three colors — black #050505, white
   #ffffff, tan #D2B48C — every other tone is a color-mix() of those three.

   The layout: no sidebar, no crowded top nav. A hairline glass top bar, an
   editorial content column, and ONE navigation instrument — a floating glass
   dock, bottom-center on every screen size, with a numbered command-menu
   popover. The same thumb-first mental model on a 27" display and an iPhone.

   Platform showcase (all native, zero build): cascade layers, CSS nesting,
   color-mix(), light-dark() auto dark mode, :has() responsive tables, Popover
   API, CSS anchor positioning, cross-document view transitions, scroll-driven
   animations, @starting-style, field-sizing, interpolate-size, subgrid,
   counters, dvh, safe-area insets.
