/* Cybereum web-font fallbacks. Linked only by the shared head fragment, next
   to the Google Fonts request, so pages that never load the web fonts
   (legal utilities, 404, internal consoles) do not get these faces: on those
   pages the "… Fallback" names in --cyb-display / --cyb-body resolve to
   nothing and the stacks fall through to the system UI font as before. */
/* Metric-matched fallbacks: while the web fonts are in flight, text is set in a
   local Arial-compatible face scaled to the web font's average advance and
   vertical metrics, so headlines keep their line breaks when the swap lands.
   Values derived from the Google Fonts latin files with fontTools. The
   Michroma fallback leaves out the symbols Michroma itself lacks (primes,
   arrows, ≤, ✓), so in display text those fall through to IBM Plex Sans
   rather than to a 142%-scaled Arial. */
