   Main Content Area

/* THE LOGIN PAGES' MAIN COLUMN -- scoped to them, 2026-10-16.
   This was a bare `.app-main`, and `.app-main` is also the APP layout's main
   region (sidebar.css:944, rendered by templates/layout/header.php beside the
   icon rail). auth.css loads from $pageStyles, i.e. AFTER sidebar.css, so on
   any app page that pulled this stylesheet in, the whole content area was
   clamped to 600px and centred -- reported on ?action=profile, which loads
   auth.css for the password-strength UI (the K-1 fix).
   Scoping the app rule instead would not have worked: max-width and margin
   have no competitor in sidebar.css, so specificity would not have undone
   them. The rule had to stop matching.
   `body[class*="page-"]` IS the auth pages: they render their own <body> with
   a page-* class (page-login, page-register, page-mfa-verify, ...) while every
   app page goes through header.php, which emits <body class="">. Verified by
   grepping every $bodyClass assignment in the codebase. */
