/* bioce.cloud apex landing — BioCE navy system (locked estate brand).
   Theme: dark only. Accent: sky #35b8f0 (+ deep #1f8fce in the one brand
   gradient). Shape rule: 28px outer panels, 18px nested media, pill controls.
   Motion: scroll-linked movement is linear (driven by main.js); entrances use
   cubic-bezier(.16,1,.3,1). Reduced motion collapses everything to static. */
