/* Oculus — industrialist page system.
 *
 * The stylesheet for every marketing page except the flight (index.html), which keeps its own
 * styles.css. Same tokens, same chrome, same components, so a visitor moving from the flight to
 * /mission never leaves the material. See brand/brand-guidelines.md.
 *
 * The brand is restraint. Structure carries the pages: type, rule, spec table, negative space.
 * Images are sparse and commanding, never decorative. This file gives structure the tools to do
 * the work Anduril lets photography do — so most sections here are built from nothing but a mono
 * eyebrow, a Cinzel headline, a column of body, and a datasheet.
