/**
 * Accessibility: text contrast (WCAG AA, 4.5:1) for two site-wide colours. Ticket #41.
 * Load AFTER app.css. Uses only the theme's own colour variables (no new hex values), so it
 * follows whatever the admin sets under Appearance > Theme colours.
 *
 * - Primary button: dark text (--text_color) on the brand green instead of white (white on
 *   #4caf50 was 2.78:1, --text_color on #4caf50 is 5.09:1). The brand green is not changed.
 * - Placeholder: --text_color mixed 70% with white (about #6b6b6b), was --text_muted #8e9cba
 *   at 2.76:1. Muted text elsewhere on the site is not touched.
