/*!
 * @fileoverview Styles for the company-comparison module (js/company-compare.js).
 *   Self-contained token set scoped to `.cc-root` (light default, dark via
 *   prefers-color-scheme + [data-theme], matching the pattern css/timeline.css
 *   uses for `.tt-tl`) so this module works standalone in
 *   dev/company-compare-demo.html without css/app.css or css/timeline.css
 *   loaded. When mounted in the real app both token sets simply coexist
 *   (distinct `--cc-*` custom properties, no collision with `--tt-*`).
 * @module css/company-compare

/* ---------------------------------------------------------------------
   Tokens — light (default), dark (prefers-color-scheme + [data-theme]).
   Chart chrome matches the dataviz skill's reference palette. The phase
   ramp duplicates css/timeline.css's validated 8-step ordinal blue ramp
   (company strips colour bars by phase "exactly as the main Gantt does").
   The categorical company palette (6 slots + neutral "other") and the
   5-step sequential ramp are validated with the dataviz skill's
   validate_palette.js — see the build report for the exact invocations.
