/**
 * 会话成本 (session-cost) — what THIS session has cost, in the money of the rule
 * that priced it, with the rule's provenance printed beside it.
 *
 * WHY THE CARD EXISTS: official DeepSeek pricing pays 0.02 CNY/M for a cache HIT
 * and 1 CNY/M for a MISS — a 50× spread inside ONE session's input. Nothing on the
 * rail folds a session into money today (会话 Token prints counts only, and money
 * in this repo has so far belonged to the Command Code plan family, which prints
 * plan occupancy, not session spend). This card is that missing reading.
 *
 * THE FOUR ELEMENTS, AND WHY EACH SITS WHERE IT DOES:
 *   `会话成本`        the blue title (the card's name, not the widget's market name);
 *   `≈$0.131`         the FIGURE row — the session's amount, or the token total when
 *                     no rule would price it (`headAfter.big`, never `value`: a card
 *                     with a headAfter head owns exactly one figure, and `value`
 *                     would be pushed into the body and printed twice);
 *   `官方价 · …`      the grey caption — the amount's PROVENANCE first (`sourceType`
 *                     localized) and the model name after it. This is the card's
 *                     discipline made visible: money never appears alone;
 *   the three rows    the buckets the amount was folded from — 未缓存输入 / 缓存读取
 *                     输出 — with each bucket's own share of the money in the
 *                     renderer's reserved third column. They sit on the card's floor
 *                     (`bodyAnchor: 'bottom'`), the posture every detail-row card in
 *                     this repo uses.
 *
 * THE `≈`: as soon as a rule publishes a peak/off-peak split, folding a whole
 * session at one band is an ESTIMATE — the session record carries no per-request
 * timestamps, so "how much of this ran inside 01:00–04:00 UTC" is not knowable from
 * the data this card is given (see `pricing.ts`). The card marks the figure with `≈`
 * and puts the full reason on hover (`cardHint`) rather than splitting the session
 * by an hour it cannot see. WHEN NO RULE MATCHES, the amount column is EMPTY — not
 * `—`, not `$0.00` — because an empty cell says "there is no number here", while a
 * zero would claim the session was free.
 *
 * TONE DIRECTION — this card is a READING, and it sets NO tone at all: spending more
 * is not bad, and a free route is not better. Literally nothing here passes a `tone`,
 * which is the whole statement. (The only colour in the card is the renderer's own
 * grey for the money column, which is a hierarchy, not a verdict.)

 * The preview's stats — declared HERE, below the descriptor, on purpose.
 *
 * `gen-registry` derives a unit's id from the FIRST `id: '…'` literal in
 * `index.ts` (dir === manifest.id === that literal). The mock rules below need
 * `id` fields of their own, so this function must not appear above the descriptor's
 * `id: 'session-cost'` in file order. A function declaration is hoisted, so the
 * reference in `example` above works. Moving this block up breaks the build.
 *
 * The mock mirrors the REAL table's shape (v2 / USD / the shipped V4.1 Flash
 * official rule) plus three decoys that make the selection visible in a screenshot:
 *   - `example-retired-v4.1-flash-twin`: same provider AND model, retired
 *     `effectiveTo: 2026-09-10`, at DOUBLE rates. If the effective-window sieve ever
 *     stops working, the preview immediately doubles — a visible failure instead of
 *     a silent one;
 *   - `example-reseller-same-model`: the same model on provider `opencode-go`
 *     (a real route on this machine) — proves the provider must match too;
 *   - `example-local-wildcard`: provider `ollama`, model `*` — proves the wildcard
 *     matches only its own provider rather than everything.
