/* ==========================================================================
   CrysMed — Provider login / register (provider-auth.html) + MFA step (provider-login-mfa.html)
   2026-10-09. Loaded after the shared head-links (so after auth.css). auth.css is shared with
   member-auth.html and is NOT edited; everything here is scoped to these two pages by being
   linked from them alone. Same approach as member-auth.css (crysmed-audit/APPROACH.md §5).

   Desktop changes approved 2026-10-09: login form spacing, "password first + code buttons"
   sign-in methods, readable links, numbered register sections + tidy file pickers, MFA code
   box, UI polish. Fields, names, actions and order of the forms are unchanged.
   ========================================================================== */
