   Accessibility note:
   --ifa-teal (#29A5A1) is ~3.1:1 on white — fails WCAG AA for text.
   We use --ifa-dark-teal (#255F71) for all interactive text/links on
   white backgrounds (~6.5:1, passes AAA). --ifa-teal is reserved for
   decorative borders, filled button backgrounds (white text), and
   focus rings where contrast is already met.
