/*
 * Version 3 -- System Health workspace.
 *
 * Continues the shell token system and the anatomy every other V3 panel uses:
 * a status line, an error region, an empty state, and a content region of
 * headed sections.
 *
 * ---------------------------------------------------------------------------
 * No traffic lights
 * ---------------------------------------------------------------------------
 *
 * The Version 2 System Health module coloured every row green, yellow, or red
 * through `status-dot-*` classes. Nothing of that model survives here. This
 * page has no severity, no grade, and no health score to colour by, so there
 * is no palette for one.
 *
 * The only two tinted things on the page are tied to *stored* facts, never to
 * a judgement this page formed, and both carry the same fact in words beside
 * them so a reader who sees no colour loses nothing:
 *
 *   .v3-sh-outcome--failure   an import whose recorded outcome was "failure",
 *                             which also reads "Failure"
 *   .v3-sh-fact--absent       storage that is not reachable, which also reads
 *                             "Not reachable"
 *
 * Both are drawn as a left border plus muted surface -- no filled colour block,
 * no dot, nothing that could be mistaken for a rating.
 *
 * Every table scrolls inside its own wrapper, so the page body never scrolls
 * sideways however wide a source filename or record key turns out to be.
