/* Enlight Model Zoo -- one stylesheet, no dependencies, light only.
 *
 * Colours come from the OPENEDGES brand sheet (site/assets/img). Only the documented
 * steps are used, with two documented exceptions:
 *
 * - Link and body text use #3A6CC4, the brand blue held at its hue and darkened, because
 *   #5087E1 itself is 3.56:1 on white and fails the 4.5:1 text floor. The true brand blue
 *   is kept for the logo, fills and borders, which is what it is for.
 * - The neutrals are derived from the blue shades (#192846 / #28466E) rather than being
 *   grey, so the page reads as one family; the brand sheet documents no neutral ramp.
 *
 * Magenta carries the one warning the pages can show, Violet is a non-encoding accent,
 * and Mint is unused for now. Nothing in the model table is colour-coded: the two
 * accuracy columns are numbers, and the reader compares them.
 *
 * The page does not follow the reader's dark-mode setting: color-scheme is pinned to
 * light so the form controls come out light too, rather than the browser painting dark
 * inputs onto a light page.
