/* DPI Site Monitoring.
 *
 * Reference lock: Linear's issue list (the screenshot Enzo supplied) for the
 * dense list — left sidebar with counts, collapsible groups with a count in the
 * header, quiet rows where colour appears only on the status glyph. The mobile
 * editor borrows Asana's iOS task sheet (rounded top, drag handle, stacked
 * field rows, primary action at the bottom).
 *
 * Role rules kept from the DPI guardrails: red is brand and alert only, never a
 * surface. Working tools stay in neutral greys. Status colours live on status
 * marks and date text, nowhere else.
