/**
 * Google Pollen API response types
 *
 * Subset-only TypeScript interfaces for the Google Pollen API `v1/forecast:lookup`
 * response. All fields are optional as a defensive measure.
 *
 * Important: `indexInfo` is **omitted entirely** for out-of-season pollen types
 * (upstream design D3/C). Every use of `indexInfo` must guard against undefined.
 *
 * Field casing is web-verified (2026-08-18). Exact casing is on the T6
 * live-verification to-verify list.
 *
 * Reference: https://developers.google.com/maps/documentation/pollen/overview
