/* --text-muted missed the 4.5:1 that WCAG AA requires for text of this size
   in every preset, ranging from 2.33:1 (monograph) to 3.50:1 (studio-modern).
   It is not a decorative colour: it carries the hero subtitle, section
   labels, album metadata and the footer links, all between 0.6 and 0.9 rem.

   Only lightness was raised; hue and saturation are unchanged, so the warm
   greys of editorial, classic and noir stay warm instead of drifting to
   neutral. Each value is checked against --bg-primary AND --bg-card, and the
   worse of the two counts.

   In minimal and monograph this pushed --text-muted so close to
   --text-secondary that the two steps became indistinguishable (#828282 vs
   #888888). --text-secondary moved along there, restoring two distinct
   levels: about 7:1 for secondary, about 4.7:1 for muted. */
