/*
 * --form-theme-color drives the "brand action" surfaces on the form:
 * submit button, selected tag pills, and the success page's submit-another
 * link.
 *
 * Default is Apple blue (light) / Apple blue dark (dark). When a form has a
 * custom button_color, templates/form.php and templates/success.php override
 * --form-theme-color via an inline <style> block on :root, which wins by
 * source order regardless of media query.
 *
 * Universal-semantic colors (toggle ON green, star gold, percent bar in-progress
 * + complete, destructive red) are NOT themable. Focus borders + glow on inputs
 * also stay Apple blue intentionally — "this is the active input" is a system
 * semantic, not a brand one. The percent bar's fill stays Apple blue too — a
 * progress indicator should read as a system control.
