/* Red Stet — shared stylesheet for the static help + science library.
 *
 * Loaded after /landing.css, which owns the site chrome (nav, footer,
 * container). Tokens come from /tokens.css, linked ahead of both — the
 * single definition shared with the app. This file declares no custom
 * properties, and neither does landing.css.
 *
 * Every rule here was extracted verbatim from the per-page \3c style>
 * blocks it replaces (Phase 6 consolidation, 2026-07-30) — 40 of the 43
 * help/science pages carried byte-identical copies. Pages keep an inline
 * \3c style> only for their own interface mocks and the one-line
 * .help-section-visual::before { content } label.
 *
 * Change a rule here and you change 40 pages. Page-specific tweaks belong
 * in that page's inline block, which is loaded after this file and wins.
