 ### Added
 - **Price mode — emit computed dollar cost instead of token counts.** New `pricing_mode` config (`"tokens"` default | `"price"`), plus `markup`, `cost_metric_code` (default `llm_cost`), `pricing_ttl_seconds`, and `bedrock_default_region`. In price mode the SDK emits one `llm_cost` event per call carrying a top-level `precise_total_amount_cents` (cost in cents, after markup) for Lago's **dynamic charge model**, with a full per-field breakdown in `properties` (value in USD, base, markup, source, per-field tokens/unit_price/cost). Live unit prices come from public, no-auth sources: OpenRouter (`/api/v1/models`) for native anthropic/openai/mistral/gemini, and the AWS Bedrock Price List **Bulk** API for Bedrock. Prices are fetched + cached on the background queue thread (never blocking the customer's call); a missing price falls back to token events and calls `on_error` (never silently under-bills). Mode and markup are overridable per-call via `extra_lago={"mode": "price", "markup": 1.5}`. Money is computed with `Decimal` floored to 12 dp, identical to the JS implementation (cross-repo golden fixture). New `pricing.py` module + `PricingProvider`; default `pricing_mode="tokens"` keeps existing behavior unchanged.
