 * TokenCostBreakdown — a `<dl>` breakdown of a request's/span's/trace's token
 * usage and USD cost: input, output, cache tokens, total, and cost. Controlled
 * and pure — the consumer supplies the numbers; nothing is fetched.
 *
 * Honest zeros (M9 SessionSummary convention): a real `0` renders `0` /
 * `$0.0000`; an ABSENT (undefined) field renders `—` (em-dash) — it is never
 * fabricated as a zero. When EVERY field is absent, an honest empty state
 * renders instead of a table of em-dashes.
