  /* Chip text. A <Tag> renders at 0.55em of a 30px root = 16.5px, which is NORMAL text
     under WCAG and so needs 4.5:1 — not the 3:1 that most deck text qualifies for. The
     chip's background is a 15% tint of its own hue, which LIGHTENS it and costs contrast
     rather than adding it, so the brand hues do not clear the floor here:
       fuchsia #EE1199 on its tint = 4.31:1   orchid #9932CC on its tint = 3.08:1
     These are the same hues lightened until they clear it with margin. The tint is
     unchanged, so a chip still reads as its brand colour.
       fuchsia 4.84:1   cyan 7.93:1   orchid 4.84:1        (test/theme.test.mjs asserts it) */
