   --gold is the FEATURE call to action (name kept for compatibility): Chamber
   blue on light surfaces, a light pill on ink, always with a small gold dot.
   On ink surfaces --primary also turns into the light pill and --secondary /
   --ghost turn light, so one markup works on both.

/* --- Focus rings drawn by :focus-within on ink surfaces --------------------
   The ring sits outside the component, on the ink, so it must be the gold
   inverse ring (14:1), not blue-600 (~2.9:1). Inside a light card or panel on
   ink the ring lands on white again, so blue comes back. Last in the file so it
   wins on order as well as specificity. */
