/* MA Tools website.
   Brand colours (owner, 2026-10-27): burnt brown, with the gold and cream of his logo.
   Contrast measured (WCAG AA 4.5:1 for text): brown on white 11.70:1, cream on brown 7.82:1,
   gold on brown 5.59:1, brown on gold 5.59:1 (4.82:1 on the hover gold). Header and footer are a darker brown. Gold on white is only 2.09:1,
   so gold is never text on white: it is a button colour, an underline or a mark.
   Logical properties (inline-start/end) so the same sheet works right-to-left. */
