/* The Supergraph - every stream held for one study on one time axis.
   Shared by /admin/supergraph and the customer page /supergraph, which both
   link it from their content.html; it was the admin page's <style> block
   until the customer page arrived, and one file keeps the two from drifting.
   Canon everywhere a component exists: .hub-wrap, .hero--george, the
   .hub-savebar study picker (blStudySavebar, controlled mode), .insp-toolbar,
   .seg, .insp-range, .tab-bar, .insp-panel, .insp-stats of .stat-card,
   .chip-group--multi, .info-tip, .notif-banner, .empty-state, .skeleton,
   .data-table, .toggle, .tag and blModal. What is here is the chart itself
   (nothing canon draws a multi-series line chart with axes, crosshair and
   events), the GSC-style metric cards that double as its legend, the event
   lane under the chart, the before-and-after panel it opens, and layout, all
   under the page's own sg- prefix and on tokens only. */

/* Series colour slots. Eight hues derived from the four brand tokens, order
   validated for colour-blind separation with the dataviz validator
   (2026-09-24: worst adjacent pair CVD 10.7 light / 9.7 dark, normal-vision
   floor 18.2 / 16.1). The brand tokens themselves sit below the validator's
   chroma floor, which a page cannot change, so identity never rests on hue
   alone: legend, tooltip and lane labels all name the series. Colour follows
   the series: a slot is kept for as long as its line is on. */
