/* Session 18 — login screen + profile logout menu. Kept in its own small file, matching this
   codebase's existing convention of one CSS file per feature area (catalog.css, import-review.css,
   duplicate-review.css, ...) rather than growing components.css.

   GOLD EDU Visual Redesign, Phase 2, Section 4 — the login screen is rebuilt as a two-panel
   shell (dark navy brand panel + white form panel). The form itself (.auth-card and everything
   inside it: #loginForm/#loginEmail/#loginPassword/#loginError/#loginSubmit) is UNCHANGED —
   only its outer wrapper and surrounding chrome moved. The old single-card .auth-card__brand
   row (GE monogram + wordmark sitting inside the form) was removed; that identity now lives in
   the new .auth-shell__brand panel instead, so it is not duplicated. */
