/* ---------------------------------------------------------------------------
 * forms.css — the site-wide FORM SYSTEM and ORDER SUMMARY.
 *
 * Loaded globally from partials/site-head.ejs, after base.css/components.css,
 * because checkout, contact, sign-in, sign-up, password reset and the account
 * pages must all look and behave identically. Extend it here; never restyle a
 * control inside a page sheet.
 *
 * Token references only — no literal colours, sizes or spacings. The one
 * exception is #fff on the accent gradient (tick marks, gradient buttons),
 * matching the existing .cta-band convention: the palette has no pure-white
 * token and white is what the gradient requires.
