/* ==========================================================
   THEME: meta
   Professional dark theme modeled on Meta Business Suite's
   design language and Meta's own dark-mode palette: near-black
   canvas, raised dark cards with subtle shadows, Meta blue
   accent, pill-shaped nav with soft-blue active state, and
   quiet, high-contrast typography.
   Surface/text values from Meta's actual dark-mode tokens
   (#18191A canvas, #242526 cards, #E4E6EB text). Accent stays
   Meta blue (#0866FF) to match the light variant's branding.
