/* LawDek v2 — plain hand-written CSS.
 *
 * Visual tokens adopted 2026-04-16 from the pre-React vanilla
 * implementation (~/lawdek/static/styles.css at commit 957b83f).
 * That design was validated with the user before the React port
 * carried it forward unchanged. This v2 port keeps the exact
 * palette, spacing rhythm, and component shapes so anyone coming
 * from the prior tool sees the same product.
 *
 * Structural classes (container, nav, brand, muted, small, tiny,
 * plain-list, link-accent, filter-bar, sev-*) stay stable across
 * the visual port.
