/* Route-family layouts for the LeetCode offline clone.
 *
 * leetcode.css carries the shared chrome, the problem set and the workspace.
 * This sheet carries the page-specific layouts the Playwright visual
 * supplement recorded for the remaining families, one block per family:
 *
 *   shell + rail   company / tag / study plan / explore  (240px library rail)
 *   collection     company + tag identity card and right panel
 *   directory      /company/ and /problem-list/ indexes
 *   studyplan      grid-paper hero, section cards, summary column
 *   explore        gradient card grid
 *   contest        checkered hero, contest cards, ranking + tabbed panel
 *   discuss        promo rail, category tabs, feed, explore sidebar
 *   profile        public profile identity column + stat cards
 *   premium        two plan cards + feature grid
 *   store          the client-side loading state the capture recorded
 *   interview      gradient hero + session panel
 *   assessment     title block + assessment card grid
 *   business       centred enquiry description
 *   support        slate search band + category grid + promoted articles
 *   article        centred legal / static prose
 *
 * Every geometry number is measured off the snapshot node rects or the
 * captured rasters listed in materials/leetcode/SOURCE_EVIDENCE.md. No remote
 * origin, no webfont, no raster background: art is inline SVG or a CSS
 * gradient authored here.
