/* ws3watch dashboard -- one committed dark-navy look, no theme toggle.
 *
 * Every colour below is a token and every token has a job. The categorical
 * slots (--s1..--s8) are the dataviz dark categorical theme, re-validated
 * against THIS surface rather than the reference one:
 *
 *   validate_palette.js "#3987e5,#d95926,#199e70,#c98500,#d55181,#008300,\
 *                        #9085e9,#e66767" --mode dark --surface "#121829"
 *   lightness band PASS · chroma floor PASS · CVD adjacent dE 8.4 PASS
 *   normal-vision adjacent dE 19.3 PASS · contrast vs surface PASS (all >= 3:1)
 *
 * The status slots are the fixed status palette; on this surface they measure
 * good 5.71 : warning 10.44 : serious 7.26 : critical 3.99 -- all clear of 3:1
 * -- and they are NEVER used as a series colour, so a colour on this page
 * either means "this series" or "this state" and never both.
 *
 * There is no light mode on purpose: this is an internal tool on the house
 * navy, and a second selected palette is a second thing to keep validated.
