/* ============================================================================
   SRR Race Meetup — styles
   ----------------------------------------------------------------------------
   The design was built as an iPhone mockup (a fixed 390×844 frame). Here we keep
   every color, font, radius and spacing from that design, but drop the literal
   phone bezel and make it a real mobile-first responsive page:

     * On a phone the app fills the screen.
     * On a wider screen it centers in a phone-width column on a warm backdrop,
       so it still feels like the designed product.

   Most component styling lives inline in js/app.js (the design itself is almost
   entirely inline-styled, so mirroring that keeps the port faithful and easy to
   diff against the original). This file holds the shared shell, tokens, fonts,
   scrollbar and animation rules.
