/* The Gift — extends carbon.css.
 *
 * The one hue in this file, and it is scoped to a single meaning: a room that is
 * live and upcoming. #F6049F exactly as specified — kept as hex rather than
 * converted to oklch, because an eyeballed conversion drifts the hue and this
 * value is exact.
 *
 * It is deliberately hotter than the rest of the palette (roughly double the
 * chroma of --ember), which is the point: everything else on this desk is
 * monochrome, so the one thing that is happening right now is the one thing
 * with colour.
 *
 * How the sign is built matters: the tube stays WHITE-HOT and only the bloom it
 * casts carries the hue. That is how neon physically works — the discharge
 * colour shows in the halo, not in the core — and it means the VLTRN "V" is
 * never recoloured, which is the house rule.
