/*
  Declared rules with real class names, not utilities.

  The style panel edits rules it can find — a page written in utility classes
  opens in Sitefold with every control dead. That is `strategy.md` §2b, and it

  artefact. This site is meant to be edited in the product it advertises.

/*
  The workspace's palette, said again in this project's own names.

  Sitefold's chrome was relifted from `cursor-colour-scheme` on 2026-09-07 and
  this file did not follow, so the page advertising the product was drawn in
  the palette the product had stopped using — a `#ffffff` panel on `#f7f7f7`
  in light, and `#202024` on `#1a1a1a` in dark. Same values here now, and the
  same two structural ideas behind them:

  **Two surfaces.** `--ground` is the canvas and `--panel` is one step toward
  the middle from it: lighter in dark, darker in light, so the canvas is always
  the more extreme end. The preview window in the hero is the panel; everything
  else is the ground.

  **One overlay at low opacity.** `--hairline` and `--field` are the ink at 7%
  and 4% rather than colours of their own, so a line is a shade of whatever it
  is drawn on — the mechanism the app's `index.css` describes at length.

  This is still hand-written CSS with real class names, for the reason below:
  the style panel edits rules it can find, and this site is meant to be
  editable in the product it advertises.
