/* Interactalk Brandkit (official, from brand sheet):
   Navy #101828, Purple #7457FF, Cyan #20C5D8, Light #F1F5F9, Inter.
   Contrast fixes (WCAG AA, normal text >=4.5:1):
   - White on #397BFF was 3.85 FAIL -> buttons now Purple #7457FF (4.62) to Dark Blue #1D4ED8
   - White on Cyan was 1.77-2.09 FAIL -> announce/buttons no longer put white text on bright cyan
   - Blue #397BFF on light #EAF2FF was 3.42 FAIL -> light tags now #1D4ED8 (5.95)
   - Muted lightened #9AA8BC (7.35) -> #CBD5E1 (11.95) on Navy
   - Cyan text on Navy passes (8.48), so cyan is kept for text on dark, not as a background for white text */
