   STYLES  —  the look of your site.
   =====================================================================
   You usually DON'T need to touch this file. Colours and the font come
   from the variables at the very top — change those to re-theme the
   whole site. Everything below them is the layout, which already works.

   Table of contents:
     1. THEME VARIABLES   ← change colours here (or pick a palette in config.js)
     2. PALETTES          ← the 7 ready-made accent colours
     3b. LAYOUT STYLE     ← "soft" / "flat" — switch the whole look
     3. DARK MODE         ← colours used when dark mode is on
     4. BASE & RESET
     5. LAYOUT HELPERS
     6. SKIP LINK & FOCUS
     7. NAVBAR
     8. BUTTONS, PILLS, CHIPS

   The palette above changes the colour; this changes the SHAPE & feel.

   live from the ⌘K command palette / the "Start here" box.

     soft  · the default — rounded corners and gentle shadows
     flat  · an editorial look — squared corners, hairline borders,
             no shadows, and a plain (glow-free) hero

   This block sits AFTER dark mode on purpose, so a flat site stays flat
   in both light and dark. Add your own variant by copying the pattern. */
