   Conaxity Status — presentation
   ═══════════════════════════════════════════════════════════════════════════
   No build step, no framework, no external requests. The page must render from
   a cold CDN cache during an incident, so everything it needs is these three
   files plus two images.

   COLOUR AND MEANING — the rule this file exists to enforce
   ---------------------------------------------------------
   Status colours are the reserved status palette (good/warning/serious/
   critical), not series colours. They are validated, and the validation says
   plainly that colour alone cannot carry the meaning here:

     · operational green #0ca30c vs major-outage red #d03b3b measure ΔE 4.1
       under deuteranopia — near-identical for the most common form of colour
       blindness, and they are the two most important states on the page.
     · degraded amber #fab219 vs partial-outage orange #ec835a measure ΔE 13.6
       under NORMAL vision — below the 15 floor, i.e. hard to separate even
       with full colour vision.

   So every status carries three channels, and colour is the least of them:
     1. a text label,
     2. a distinct icon shape,
     3. in the history strip, a distinct texture — solid / 45° / 135° /
        cross-hatch / hollow — that increases in visual weight with severity.

   Remove any of those and the page becomes unreadable for a large minority of
   its audience. Do not "simplify" the strip back to flat colour blocks.
