/* TrustPath join page. Plain CSS on the F-Secure design-system tokens (fs-ds-shadcn,
   as synced into the mockups' ds/ bundle), with the accessibility overrides the
   mockups documented (README "Upstream fixes for fs-ds-shadcn"):
   - input/outline strokes #7A8699 (3.69:1 on white; DS --input #E2E8F0 is 1.23:1)
   - focus: 2px solid --fs-blue-500 outline, offset 2 (6.8:1; DS ring is 1.96:1)
   - muted text on muted surfaces --fs-gray-600 (6.92:1; DS pair is 4.34:1)
   Light theme only, as in the mockups. No inline styles anywhere (strict CSP). */
