/* Altus look (v1.5, PM decisions of 2026-10-17): the teal scheme in a light and a dark mode, made for long hours on screen.
   - Light: dark teal frame (top bar), soft off-white workspace, white cards; text in dark teal-grey, never pure black.
   - Dark: deep teal-grey surfaces (never pure black), text in soft white; accents toned down so nothing glows.
   - The signature: a thin cyan > aqua > lime line under the top bar; the logo's red summit.
   - Text in Inter (made for screens); the name and headings in Outfit. Both are open-licence files in /fonts (OFL-*.txt).
   - The metamodel's layer colours are data: light mode shows them as stored, dark mode lightens them on screen (layerColor() in app.js).
   Mode: "auto" follows the computer; the user menu can set light or dark (data-theme on <html>, set by theme.js). */
