/* SignalSolid Experience 2026: the last stylesheet in both shells.
 *
 * Holds shared layout, rhythm and touch behaviour. Colours come only from the
 * --ss3-* theme tokens, so light and dark stay correct without per-theme rules.
 * !important appears only where a legacy layer already uses it for the same property.
 * Breakpoints: 980px (app drawer), 640px (phone), 380px (small phone).
