/* LeetCode offline clone stylesheet.

 * Every colour, size, radius and weight below is taken from the computed-style
 * and geometry fields of the Playwright evidence snapshots, or measured off the
 * captured rasters. Nothing is loaded from a remote origin: no webfont, no
 * image host, no icon CDN. Icons are inline SVG in the templates.
 *
 * Layout order: tokens, resets, marketing chrome, home, application chrome,
 * problem set, workspace, account pages, member pages, boundary pages.
