/* =========================================================
   Lio Fernández Roca · token system v3
   Paper editorial ground, ink type, cobalt-blue accent
   (sampled from his own jacket), cutout portrait signature.

   v3 changes from v2:
   - Display face swapped to Piazzolla (named for Astor Piazzolla,
     the Buenos Aires tango composer) in place of Bodoni Moda /
     Fraunces / Frank Ruhl Libre. It is an editorial serif with real
     character and a personal tie to Lio's Buenos Aires roots,
     rather than a font picked for looking "designed."
   - --accent-bright split into a light-background use (unchanged
     hue) and a dedicated dark-background text tone, because the
     old value only hit ~3.5:1 against --ink (fails WCAG AA for
     text; fine for large text/UI only). New value verified by hand
     against the WCAG relative-luminance formula at ~4.6:1.
   - --ink-faint darkened from #8A8D8F to #6B6E71 for the same
     reason (old value was ~3:1 on paper, used for captions/dates).
   - Logo wall rebuilt as a typographic client index (no hotlinked
     icon-only marks, no bordered pills).
   - Header now carries a role/location tagline next to the
     wordmark instead of sitting flat with just a name.
   - Added a skip link, tightened focus states, and an extra
     small-phone breakpoint.
