 * Redesign 2026-09-22. Screen F is a reference document, so it is laid out
 * as one: an "On this page" index (a sticky rail on wide screens) beside one
 * card per section, in the order the rating pipeline runs.
 *
 * What it replaces, MEASURED at a 1440 px viewport: nine collapsed <details>
 * hairlines, and one generic `.evidence-table` whose cells were all `nowrap`
 * except the first (`word-break: break-word`). Long prose cells pushed three
 * tables to 1,545 / 2,092 / 3,079 px and the auto table layout squeezed the
 * one breakable column to ~21 px, stacking identifiers one character per
 * line. Every table cell now declares a role -- identifier (.cell-id),
 * number (.num), prose (.cell-prose), meta (.cell-meta) -- and the
 * prose-heavy lists (gates, detectors, change log) are entry lists.
 *
 * Wrapping rule used throughout: `overflow-wrap: break-word`, never
 * `anywhere`/`break-all` inside a table or flex row. break-word still
 * breaks a token that would overflow its line, but it does NOT lower the
 * token's min-content size, so it can never collapse a column. */
