/* PayPanda — unified checkout page stylesheet.
   Used by every /pay/<merchant>/index.html. To add a new merchant page,
   copy an existing pay/<merchant>/index.html and change only:
     1) the three --brand-* variables in its inline <style id="brand-theme">
     2) the logo, favicon, brand name text, and support links
   Every merchant then shares this exact layout, spacing, and behavior —
   no more copy-pasting or drifting per-page CSS. */
