   Setpaid design system
   --------------------------------------------------------------------------
   Layered on top of Bootstrap 5.3. The goal is a single, cohesive brand —
   a money-green identity that reads the same across the marketing landing
   page, the authentication screens, and the in-app pages.

   Brand anchor: the favicon — a white "$" on a money-green rounded square.
   Everything here derives from that mark.

   Structure:
     1. Brand tokens + Bootstrap theme overrides (kills the default blue)
     2. Typography
     3. Buttons
     4. Navbar + brand mark
     5. Cards, dropdowns, forms
     6. Marketing surfaces (hero, features, steps)
     7. Auth + account management
     8. Status badges
     9. Footer
    10. Motion (reveal-on-scroll, reduced-motion safe)
   ========================================================================== */

/* 1. Brand tokens + Bootstrap theme overrides -------------------------------
   The green scale mirrors a standard 50–900 ramp. Two contrast rules keep us
   WCAG AA: solid fills that carry white text use green-700 (#15803d ≈ 5:1 on
   white); only large text, icons, borders and decorative fills use the
   brighter green-600/500. */
