/* ============================================================================
   seas-site/motion.css — authored-code lane (SEAS-D-11), owner: LANE A (append-only).
   The entrance layer: seas-rise / seas-drift + reduced-motion gates (I-26/I-27,
   SEAS-D-8). LOAD-TIME keyframes, NOT scroll reveal — zero IntersectionObservers
   exist live; a builder adding scroll triggers is a process failure.
   NOT built with Bricks interaction effects (wrong curves — BRICKS_ADAPTATION §1e).
   Rules re-authored verbatim from live-built.css; durations/easings are the seeded
   motion tokens (no raw ms in any Bricks control — the raw values here ARE the
   authored lane, per INTERACTIONS.md lane column).
