/* frampifyd theme layer (2026-08-15 htmx+material plan WS-1).
 *
 * This file is FIRST-PARTY and load-bearing for the G-1 hybrid strategy:
 * every domain-specific style lives here as a .f-* class over Beer CSS's
 * MD3 custom properties, so beer-*.min.css can later be swapped for a
 * hand-rolled sheet without touching template semantics. Templates may use
 * only the Beer classes listed in BEER-SUBSET.md plus the .f-* classes
 * below (grep-guarded by ttu_template_assets_test.go).
 *
 * Light/dark: Beer CSS themes itself from the device color scheme; the
 * semantic tones below do the same via prefers-color-scheme. There is no
 * manual theme toggle (plan G-11).

 * redundant — and two superimposed dashed lines with different dash
 * phases union into a solid-looking segment. Drop the overlay entirely in
 * the empty state; the input's own dashed border spans the full edge.
