     The dark-mode --color-success/--color-error (above) pass AA as text on
     the dark backgrounds, but light mode inherited the SAME two values, and
     they fail AA as text on --color-bg-primary (neutral-50 #f8f9fa):

       --color-error   #ef4444 on #f8f9fa  →  3.76:1  (needs 4.5:1)
     mywateer-app hit exactly this and fixed it (src/constants/theme.ts,
     Colors.light.success/danger, audit A3 2026-09-20) with darker tones that
     clear AA on both its `background` and `surface`:
       #047857 on #f8f9fa  →  4.96:1   #c62828 on #f8f9fa  →  5.09:1
     Reused verbatim here rather than re-deriving a third pair — this is a
     token *value* override for light mode, not a new token name, so any
     existing `var(--color-success)`/`var(--color-error)` usage picks it up
     automatically. Dark mode is untouched (already correct, see above). */
