/* Shared across login.html, index.html, admin.html (same precedent as
   ui-dialogs.css). Fixed-position, independent of each page's own header
   -- login.html has no header at all, so this guarantees pixel-identical
   placement on all 3 pages instead of two different layout code paths.
   Only uses CSS variables confirmed present with the SAME name in
   index.css, admin.css, AND login.css (--bg, --ink, --accent,
   --accent-ink) -- other variables (--panel/--card, --rule/--card-border)
   differ in name between login.css and the other two, so are avoided
   here. */
