/* HowMuchie marketing site
 * ============================================================================
 * COLOUR TOKENS
 * Ported verbatim from the shipping app's single colour source:
 *   /Users/waynefoo/Flutter Projects/HowMuch/frontend/lib/theme/app_colors.dart
 * Warm-paper backgrounds, warm-brown ink, one orange accent. Blue is links only.
 *
 * Every colour on this page resolves through a token in the :root block below.
 * There are no raw hex literals outside it — so re-skinning the site to a
 * different brand identity is an edit to ONE block, not a sweep through the
 * stylesheet. (See the open brand question in README.md.)
