/* ==========================================================================
   corneliaschneider.github.io — shared stylesheet

   Palette and page architecture follow the design you liked (paper ground,
   burgundy accent, full-bleed images); the type scale and the section
   structure are the tighter ones from the first draft.

   All colours are variables in :root — change them here and the whole site
   follows.
