// The share dialog's link row says two things with colour alone: a PROTECTED link's lock is lit, and
// Revoke is the destructive one. Both colours once sat on the button, where the ghost variant's own
// colour class outranks them (clsx does not merge Tailwind), so a password-protected link looked
// unprotected and Revoke hovered neutral. They live on the ICON now; this pins them there.
