/* x-manager — Apple design language.
 *
 * Tokens are named after the design doc's own roles, so a value is changed in
 * one place and every surface follows. Two deliberate departures from the doc,
 * both measured rather than preferred:
 *
 *  1. `--ink-muted` is #6e6e73, not the doc's ink-muted-48 (#7a7a7a). Measured:
 *     #7a7a7a is 4.29:1 on white and 3.94:1 on parchment, both below the 4.5:1
 *     AA floor for body text. #6e6e73 is 5.07:1 / 4.66:1. #7a7a7a is kept for
 *     disabled states, where AA exempts it.
 *  2. `--ok` / `--danger` are darkened for use as text on light surfaces. The
 *     doc defines no semantic status color, and a traffic-light green or red
 *     that reads well on a near-black tile is unreadable as text on white.
 *
 * The doc's own rules are otherwise followed exactly: one accent, one shadow
 * (on product imagery only), no gradients, no shadows on chrome, weight 500
 * absent from the ladder, and full-bleed tiles that never round their corners.
