   corporation1 — Global Stylesheet
   Aesthetic derived from the brand mark: a hairline circle bisected by a
   vertical line, rendered in "bone" on warm espresso-black. The whole site
   is monochrome, austere, and typographically driven (Space Grotesk + Inter)
   — the restraint is the point.
   Structure:
     1. Design tokens
     2. Base / reset
     3. Layout helpers
     4. Ambient light
     5. Navbar
     6. Buttons & pills
     7. Hero
     8. Sections & cards
     9. (see 14: apps, legal pages, contact)
    11. Footer
    12. Animations
