 * Shared base for the standalone subsidiary one-pagers

 * These pages are deliberately NOT part of the main site's design-token
 * system (public/assets/css/base/tokens.css) — they have no shared
 * header/footer and are meant to look like their own thing per company.
 * The one deliberate thread kept for brand continuity is the type family
 * (Space Grotesk / IBM Plex Sans, same as the main site) — everything
 * else (palette, spacing scale, radius) is intentionally NOT reused here,
 * so a per-company override file is free to define its own without
 * fighting inherited values.
 *
 * Load order in each company file: _base.css, then that company's own
 * <slug>.css.

 * point is a constant "this isn't final yet" notice, not a splash
 * screen that scrolls away. Semi-transparent so the real design
 * underneath is still visible through it — a notice taped ON TOP of the
 * page, not a blocking loading screen. z-index sits above the gallery
 * lightbox (999) since it's meant to cover literally everything.
