/* =========================================================================
   LampCal — site stylesheet (v8)
   Layout and typography modelled on anthropic.com: an ivory page, a geometric
   sans for headings, a serif for statements, pill navigation, soft beige cards,
   mono labels on hairline rules, left-aligned two-column page openings and a
   "learn more" row of square illustrated tiles.
   LampCal's own colours, logo and original footer are kept.

   TYPE SCALE (every text on the site uses one of these)
     --fs-hero      opening statements (sans + serif)    28 → 40px
     --fs-display   page titles                           36 → 56px
     --fs-h2        section headings                      30 → 48px
     --fs-h3        card headings                         19 → 21px
     --fs-lead      serif intros                          18 → 22px
     --fs-body      body text                             16.5px
     --fs-small     card text, lists                      14.5px
     --fs-label     labels, nav, meta                     13px
