/**
 * Tuning for the transcript notice block.
 *
 * The notice sits at the transcript's margin — a `source · title` headline and
 * rows behind the shared transcript rail, each row led by its own severity
 * glyph. The glyphs come from the shared vocabulary, the roles from the shared
 * rail map, and the rail glyph from the `chrome` config, so a notice reads like
 * the tool results around it.
 *
 * Severity reaches two surfaces: the rail (the block's worst severity) and the
 * headline's title (the notice's own). A row carries no colour of its own, so a
 * notice reporting one success and one failure stays readable as a list.
