/* ==========================================================
   BUTTONS — unified editorial button system
   ----------------------------------------------------------
   Variants:
     .btn--solid    — ink fill, bone text, oxblood ink-fill from
                      bottom on hover. Arrow icon slides 4px right.
     .btn--ghost    — outlined, ink text. Ink fills from left on hover.
     .btn--text     — text link with hairline underline that
                      draws in from the left on hover.
     .btn--small    — compact (filter pills, admin tabs).
     .btn--icon     — square icon-only (lightbox arrows, scroll-top,
                      accordion). 44×44px hit-area minimum.
   Driven entirely by tokens — never hardcode hex.
