/*
 * Version 3 -- Readiness workspace.
 *
 * An operational command centre, built on the existing shell tokens and the
 * anatomy Home and the vendor dashboards already use. Dense enough to scan a
 * hundred-athlete squad, plain enough that nothing decorative competes with the
 * data.
 *
 * ---------------------------------------------------------------------------
 * No colour on this page carries meaning on its own
 * ---------------------------------------------------------------------------
 *
 * There is no red, amber, or green status anywhere here, because there is no
 * governed status to express. `PERFORMANCE_KNOWLEDGE_MODEL.md` §11 forbids a
 * traffic light without every contributing figure, window, baseline, and
 * confidence shown alongside, and names readiness as the reason that rule
 * exists.
 *
 * The two tints that do appear are reinforcement, never signal: a system cell
 * with data is emphasised beside the record count that says the same thing, and
 * the selected row is marked beside an `aria-current` the browser announces. A
 * reader who sees no colour loses nothing.
 *
 * The confidence dot is likewise decorative -- the level is spelled out in the
 * same sentence, exactly as Athlete 360 does it.
