 * Palette usage guard (accessibility — keep both palettes AA)
 * ---------------------------------------------------------------------------
 * accent (#C24A22 default / #E8825A midnight-steel) is a LARGE-TEXT / dark-band
 * / decorative color only. In the DEFAULT palette accent on base is 4.59:1 and
 * on tint is 4.18:1 — both BELOW the 4.5:1 AA threshold for small body text.
 * Never set accent as the text color on small body copy over base or tint; use
 * primary (5.9:1 on base) or contrast instead. accent as large text (>=24px or
 * 19px bold) and on the contrast band remains AA-safe.
 * Icon SVGs hardcode stroke #22668A; the Midnight Steel variation inverts them
 * via styles.css so they clear 3:1 non-text contrast on the dark cards.
