/*
 * H&P Employee Auction - shared theme and component vocabulary.
 *
 * Tokens are adapted from the My H&P Revamp theme (navy #1e3a5f, system font
 * stack). Light/dark follow the OS unless <html data-theme="light|dark"> forces
 * one (set by HP's theme toggle, stored in localStorage "hp-auction-theme").
 *
 * Contrast: every text/background pair below meets WCAG 2.1 AA (4.5:1 for
 * body text) in both themes. Status is never conveyed by color alone: pills
 * always carry a text label.
 *
 * CSP: this file is the only stylesheet mechanism besides page CSS in /css;
 * pages never use style="" attributes. See docs/FRONTEND.md for usage.
