/*
 * The palette is the client's, not a new one: every value below is a constant in
 * `crates/cartopolis/src/systems/gui/theme.rs`, which is the only place UI colour
 * lives in this project. A fresh hex here is how the chrome drifts — the loader
 * CSS in `crates/cartopolis/index.html` is kept in step with the same table for
 * the same reason.
 *
 * The contrast ratios in that file's module note carry over unchanged, since the
 * pairings do: --text on --surface is 11.9:1, --text-dim 6.9:1, --accent-text
 * 6.9:1, and --ink on an --accent fill is 5.9:1.
