/* jacobsaunders.xyz — editorial/print-inspired, deliberately not the usual
   flat-card look. No external fonts, no JS, no frameworks.

   To restyle, change the custom properties in :root. Everything else derives
   from them. Layout is a two-column rail + column on wide screens, stacking
   to one column on narrow ones.

   NOTE: the CSP forbids inline styles (style-src 'self'), so all styling
   must live in this file — do not add style="" attributes to the HTML. */
