   Operations OS — نظام العمليات · page layer v0.2 (2026-10-03)

   Loads after the shared sheets (styles.css · header.css · footer.css), which are byte-identical to
   Revenue OS, Reputation and Content OS. Everything specific to this page lives here, prefixed `ox-`.

   THE DRAWING ALPHABET (page master, header block) — it is what makes the page hard to copy:
   - a person or a team is a CIRCLE;
   - the request is a SQUARE;
   - ownership is the square with exactly ONE circle — a solid line to it in the hero drawing, inside it on
     the rail;
   - CORAL is drawn only for an exception or a human decision (Architecture §10), and an exception is a
     coral-EDGED SQUARE, never a circle. The primary call to action and the shared focus ring are the
     documented exemptions. Calm (resolution, ownership held) is sage.

   COLOUR VALUES are measured against the ground they land on: scaffolding lines may sit near 1.8:1, but
   anything a reader must resolve is ≥ 3:1, and every var() used here is defined here or in the shared
   sheets — a var() with no definition draws nothing, silently.

   MOTION: three signatures — the ownership line draws in the hero, the star becomes a rail, the request
   walks the example track and stops. Each plays ONCE when its own drawing is seen, then holds its end state;
   replay is a button. Nothing loops. #status has no motion at all. Every animation has a reduced-motion
   path and the manual switch (html[data-motion="off"]).
