/* ==========================================================================
   KosherVyosher — Menahel Portal ("The Register", consumer cut)
   Friendly consumer-grade finish on the register skeleton: sticky white
   masthead with the real logo and tinted-pill nav, Inter type, committed
   blue, soft sheets, roomy tables, colored status chips.
   Shared by index.php (login) and every page via partials/layout.php.

   Note: legacy token names are kept so per-page styles keep working —
   --kv-black now means "ink", --kv-offset-shadow is a normal drop shadow.
