/* psh manual — shared styles.
   Matched to the rowan.id.au app scheme: light, warm, SF system font, rounded
   cards, soft shadows. psh gets its own accent (indigo/violet) so it reads as a
   distinct product alongside MacBurger (orange) and PROS (blue). Code blocks stay
   dark — a deliberate "terminal" note on the light page. Retune tokens in :root. */
