 *
 * Active state: we use active:bg-{semantic}/75 + active:scale-95 + inset shadow only (no active:bg-none).
 * In the showcase app one Tailwind run can emit utilities in an order where primary wins; in consumers
 * the prebuilt nqui styles load order can make active:bg-none win and clear the fill. Omitting
 * active:bg-none keeps the pressed background and shrink animation consistent everywhere.
 *
 * Disabled filled buttons: do not use transparent bg + *-foreground text — on light surfaces
 * primary-foreground reads as white-on-white. Use bg-muted + text-muted-foreground + border-border
 * so disabled state works on any theme without extra wrapper styles.
