/* ============================================================================
   GLOBAL — shared across every template
   Loaded site-wide. If a rule appears on more than one template, it belongs
   here and nowhere else.

   SCOPE: base typography is gated behind body.bc-type, which functions.php
   currently adds on blog templates only. Shop, checkout and homepage keep
   the Elessi look untouched. One line in bc_body_classes() switches the whole
   site over — the token values do not change.
