   Diagnostix360 — "Signal" design system  (v11)
   Static site for Cloudflare Pages. No frameworks, no external requests.

   v11 changes
   -----------
   1. Real self-hosted webfonts (Space Grotesk / Inter / IBM Plex Mono, OFL).
   2. Screenshot components rebuilt: every screenshot is shown WHOLE.
      No fixed pixel heights, no object-fit:cover cropping.
   3. Numbered section spine so the page has a readable structure.
   4. Dead rules removed.

   THE FIX. Previously .shot img /    screenshot was scaled up to fill the box and then clipped — up to 46% of
   the screen was cut off, and the three treatments disagreed with each other.

   Now the container carries the *source aspect ratio* and the image is
   contained inside it. Nothing is ever cropped or stretched. Scale is
   controlled by one variable, --dw, so every screenshot on the site is
   sized by the same rule.
