/* Unwrapped Food.
 *
 * One stylesheet, self hosted, no external origins at all. The page renders
 * with no third party connection, which is good for speed and removes a whole
 * class of supply chain risk.
 *
 * Two rules run through the design:
 *
 * 1. Severity is shown with colour. Evidence strength is shown with a dot
 *    meter. Keeping them in different visual languages is what stops a reader
 *    collapsing the two axes into one impression of danger.
 * 2. Colour is never the only signal. Every severity carries a word, every
 *    nutrient band carries its band name, and the dot meter carries a label,
 *    so the page works in greyscale and to a screen reader.

/* --- Dark ----------------------------------------------------------------
 *
 * The palette and nothing else. Every rule above takes its colour from a

 * the two cannot drift apart. The test suite holds that line.
 *
 * Three things deliberately do not invert:
 *
 *   - NOVA group colours are an identity carrying white numerals, and a mid
 *     tone reads on either background.
 *   - The plate behind a product photograph. Most Open Food Facts pictures
 *     are shot on white and cut out badly, so a dark plate would ring every
 *     pack with a white halo. It dims instead of flipping.
 *   - Severity keeps its hue. Green, amber, orange and red have to mean the
 *     same thing in both themes; only lightness moves, and it moves far
 *     enough that each still clears 4.5:1 on the surface it sits on.
