/**
 * brand/theme.css — QrLinkWave shared design tokens + base components.
 * ------------------------------------------------------------------
 * Single source of truth for every surface: marketing site, app,
 * transactional emails inherit these hex values by reference (E1 fix).
 * Canonical values (resolved against Brand_Kit.png vs shipped CSS):
 *   --ink    #0B1023   (shipped value — kept; PNG label was the stale one)
 *   --violet #6E32FF   (shipped value — kept; PNG swatch label was the stale one)
 * Do not duplicate these tokens in any other file — link this stylesheet
 * (or require brand.php, which prints the same tokens for inline/email
 * contexts where an external stylesheet isn't available) instead.
