/* The charts in "CI now" (views/infrastructure-charts.js, infrastructure-charts.logic.js).
 *
 * PALETTE. Runner hosts take the fixed categorical slots 1 to 7 (HOST_SLOT in the logic), a host the
 * page does not know, a paused or an offline runner slot 0 (grey). Light and dark are each their own
 * steps of the same seven hues, checked with the colour-blind and contrast validator against this
 * page's surfaces (#ffffff light, #241f33 dark) on 2026-10-27: every adjacent pair passes in both.
 * The heavy and light job tags are one hue in two steps (an ordered pair, checked the same way), so
 * they never look like a runner. Status colours (normal, long, very long, past its usual length,
 * stuck) are fixed and always come with an icon and a word. Text is never drawn in a series colour.
 * Data-viz colours are outside the cross-project theme sync (firebase-changelog-service/CLAUDE.md). */
