   Oceantic — page components
   Loaded after styles.css, never instead of it. Every token, every rule and
   every primitive (.wrap, .rule, .gap, .h2, .lead, .grad, .panel, .tag …)
   comes from the base sheet; this file only adds the shapes the landing page
   never needed — a matrix, a pipeline, a positioning field, a timeline, and
   the slide geometry the investor deck is built from.

   Same constraint as the base sheet: neutral ladder plus one hue. The only
   second colour is #c0553a, already in the system as the "drifted" mark.
