   11th Hour Ventures — The Startup Provisioning Company
   styles.css · concept build C1

   THE IDEA: read the mark literally. The frame is your company, the
   open corner is the gap, the red tile is what we provision. Every
   large visual on the site is that sentence drawn at a different scale:
   the hero canvas assembles it, the diagnostic sheet finds it, the
   approach drawing builds it, the About clock times it.

   Grammar: an engineered document. Numbered sheets ("03 / 07",
   renumbered by script.js), hairline rules, a title block in the
   footer. Radius is 2px by intent; no gradients; the accent is
   emphasis only. Orbitron for headings, Roboto for everything else.

   Sections of this file:
     0. Tokens (light) + dark overrides + scoped surfaces
     1. Reset / base
     2. Utilities: container, mark, links, labels, chips, tags
     3. Header, nav, jump button, theme toggle, scroll meter
     4. Sheet grammar: sections, bands, sheet heads, statement
     5. Home hero: canvas, display type, HUD, lexicon
     6. Home 01: the diagnostic
     7. Home 02: the approach drawing
     8. Home 03: what we provision
     9. Home 04: track record readouts
    10. Home 05: case files
    11. Home 06: the lab
    12. Forms and contact
    13. Inner pages: hero, on-this-page list
    14. Services: matrix, flow, modes, pipeline
    15. About: blocks, the clock, the system, principles, partners
    16. FAQ
    17. Build routes compared
    18. Case studies
    19. Figures (GIFs and video)
    20. Dialogs and the jump palette
    21. Footer and title block
    22. Reveal-on-scroll
    23. Responsive
    24. Motion preferences, view transitions, print
