/*
 * Code token colours, after the avanserv VS Code theme.
 * Syntax-Source: avanserv/vsx-avanserv-theme@433faca, themes/AvanservDark.json
 *
 * Slate takes the vsx colours as they are, except comments and punctuation: vsx #63697d is
 * 3.2:1 on the dark code ground, so they use --color-content-faint (ink-500). vsx has no light
 * theme; the light values keep each hue and lower its OKLCH lightness until it holds 4.6:1 on
 * the card under a highlighted line. tests/test_syntax.py compares the slate values with vsx.
 *
 * A highlighted line is a neutral band, not the accent wash, which drops dark keywords below AA.
 * In slate the band is recessed rather than lifted: any lighter band takes comments under 4.5:1.
