/* Shared base styling for the analysis pages.
 *
 * WHY THIS FILE EXISTS
 *   filers.html, expansion.html, distributions.html, live.html and
 *   rankings.html all link /style.css and all style themselves through
 *   var(--bg), var(--text), var(--border) and so on. The file was never
 *   there -- it returned 403 -- so every one of those variables resolved to
 *   nothing and the pages fell back to black-on-white browser defaults while
 *   the index rendered dark. Same site, two different looks, depending which
 *   page you landed on.
 *
 *   The tokens below are lifted from index.html, which carries its own
 *   complete inline stylesheet. index.html is deliberately left alone: it is
 *   generated with its styles inline and does not link this file.
