/*
 * Team Manager dashboard.
 *
 * Colours follow the project's data-visualisation palette. Availability is a
 * *status* encoding (good / critical / neutral), not a categorical one.
 *
 * Important accessibility note on the availability colours: measured against
 * both surfaces, good (#0ca30c) and critical (#d03b3b) sit at CVD Delta E 4.1
 * under deuteranopia — far below the 8 threshold. Red/green is the natural
 * reading of "in" and "out", so we keep it, but that means hue can never be
 * the only channel. Every availability value therefore also carries a glyph
 * and a written word, and every meter segment carries its own number. Colour
 * is strictly redundant here; remove it and nothing becomes unreadable.
