/* PaisaWalla — one stylesheet, no build step, no CDN, no webfonts.
   Design tokens are the spec's (§3). Two corrections, both measured:

   --muted was #6C7873 → 3.94:1 on cream. That is below WCAG AA for normal text (4.5:1), and
   it is the colour of the standing disclaimer at 13px on every page. The spec's own compliance
   rule says a disclosure must never be "fine-print grey-on-grey" (§8) and the acceptance
   criteria ask for Accessibility ≥95 (§11), so the token could not stay as written.
   #626E69 keeps the hue and clears AA: 4.56 on cream, 5.14 on card.

   --gold is an ACCENT, NEVER TEXT: 2.19:1 on cream fails even the large-text bar. It is used
   here only as a rule and a filled block.
