/* ============================================================
   pages/destinations.css

   The searchable global destinations directory
   (staging/destinations/index.html, generated by
   scripts/theme_v2/build_destinations.py).

   Layout:
     - .otg-dest__hero      flat structured hero (eyebrow + H1 + lede + stat)
     - .otg-dest__search    sticky search bar: input + continent chips + count
     - .otg-dest__results   continent groups, each a responsive grid of
                            country cards; subregion chip-links nested per card
     - .is-hidden           the single toggle the filter JS uses

   Kayak-style enterprise-minimal: flat hairline surfaces, cool greyscale,
   one font, no photography on this index (kept text-forward so 195+ entries
   stay lightning fast). Every value uses var(--otg-*) tokens.
