 * A resolved set of Peach colour tokens. Peach is dark-only, so [peachDark] is
 * the sole factory; the indirection survives because it also carries the live
 * accent, which the [PeachColors] singleton cannot.
 *
 * Accent-derived tints (glow, border, dim …) are NOT stored here: they are the
 * `Color.peachGlow()` family in AccentColors.kt, computed from the current accent
 * at the call site so they re-derive whenever the user changes their accent.
