// ============================================================================
// Canonical lifecycle-status registry.
//
// Five pages (deliveries, orders, ordersDetails, Tenants, and the dispatch
// panels) each carried their own private `STATUS_META` map. They agreed on the
// hexes but disagreed on everything else — orders.js keys off the raw
// `GET /admin/bookings` enum (`pending_pickup`, `miler_assigned`, …) while
// deliveries.js keys off api.js's generic `pending`/`accepted`/`delivered`
// mapping, so the same order rendered under two different labels depending on
// which page you were looking at.
//
// This module is the one place that knows what a status LOOKS like. It does
// not know what a status MEANS to a given page — the pending/accepted bucket
// rules stay in each page's query layer, because those genuinely differ (see
// the long comment above orders.js's STATUS_TABS).
//
// Each entry carries four renderings of the same state so a page never has to
// pick a colour by hand:
//   color  — hex, for the surfaces that take a raw accent (StatCard,
//            AccentAvatar, chart series). Matches CLAUDE.md's status palette.
//   badge  — Astryx <Badge variant>. Non-semantic tinted variants on purpose:
//            per Astryx's Badge guidance the solid semantic variants
//            (success/warning/error) are for states that demand attention, and
//            a table where every row shouts is a table where nothing does.
//            `cancelled` is the one state that keeps a loud variant.
//   dot    — Astryx <StatusDot variant>, which only has five values, so
//            several lifecycle states collapse onto `accent` here.
//   icon   — react-icons component (not an element) so callers size it.
//   hint   — a two-or-three word definition of the state, for surfaces that
//            show the name and its meaning together (SegmentCard's `range`).
//            Deliberately terse: it sits beside the label, not under it.

// Raw backend enums that render as one of the states above. Kept separate from

// "is this a known alias?" rather than silently falling back.
//
// The booking enums come from `GET /admin/bookings` (confirmed live — see
// orders.js). `converted_to_consignment` stays `accepted` HERE and only here:
// this registry renders the badge on the Orders page, whose operator workflow
// treats everything before hand-off as assigned.
//
// The DELIVERIES page classifies the same status as `picked`, in
// `mapBookingStatusToDeliveryStatus` (api.js) — deliberately, and the two are
// not in conflict. Deliveries tracks the rider's engagement, and
// doormile-flow.md §5 is explicit that `pickup-complete` is what converts a
// booking into a consignment, so on that page the parcel is in the rider's
// hands. Orders tracks the operator's action, where it is still just assigned.
// Same booking, two questions, two answers. Don't "fix" one to match the other
// without re-reading root CLAUDE.md on why the two taxonomies exist.
