/* ---------------------------------------------------------------------------
   Subset icon fonts — replaces bootstrap-icons.css and fontawesome all.min.css.

   The full versions shipped ~2,000 Bootstrap Icons and ~2,000 Font Awesome
   glyphs; this site uses 79 and 21 respectively. The two woff2 files were
   subset with pyftsubset to exactly those glyphs:

     bootstrap-icons.woff2   127.3 KB -> 7.4 KB
     fa-solid-900.woff2      153.5 KB -> 3.4 KB

   font-display is swap rather than block. With the originals, block was the
   safer choice because the fonts were large enough that a fallback flash was
   likely; at 7 KB and 3 KB they arrive with the stylesheet, and swap stops
   Lighthouse flagging up to 3 s of invisible glyphs.

   REGENERATING: if you add an icon that is not in the lists below it will
   render as a blank box. Re-run the subsetting step with the new glyph included,
   or temporarily re-link the full vendor stylesheets in the page <head>.

   2026-07-25: added bi-columns, bi-distribute-horizontal, bi-grid-3x3 and
   bi-ladder (used by the homepage's JS-rendered "Related articles" blog
   cards) and re-subset bootstrap-icons-subset.woff2 to include them —
   these were missing from the original 75-glyph subset, which meant they
   silently rendered as blank boxes anywhere the full vendor CSS wasn't
   also loaded as a fallback.
