/* OnnGrid dashboard — business-intelligence UI.
 *
 * Palette tokens are the dataviz reference palette. Categorical series live in
 * --series-1..8 in FIXED order; status in --status-*; ink/surface/grid follow
 * the reference chrome. Dark mode is a designed set (not an auto-flip): each
 * series slot is the dark step chosen for the dark surface #1a1a19.
 *
 * Palette validation scope (scripts/validate_palette.js): the set is validated
 * for ADJACENT use (line/bar/stack — the only multi-series forms shipped here),
 * NOT for all-pairs. Both modes clear the adjacent CVD floor; a few slots sit in
 * the 8–12 ΔE floor band (dark) or below 3:1 contrast (light --series-3 yellow,
 * --series-7), so those are relieved by the table-view twin on every chart plus
 * direct labels — never color alone. Do not plot non-adjacent slots (e.g. 1+5)
 * together without secondary encoding.
 *
 * Evidence vs context stays visually unmistakable:
 *   evidence — solid accent stripe (steel blue, series-1)
 *   context  — dashed stripe + amber caution (investigative-context-only)
