/**
 * Adapter for CSO PxStat table EBA02 "Domestic Building Energy Rating" —
 * annual counts of BER certificates by rating, area, and period of
 * construction. CC-BY 4.0. This gives area/era-typical BER context; it can
 * never tell you a specific home's rating (SPEC §4.7).
 *
 * Matrix and dimension codes pinned 2026-07-11 from
 * `PxStat.Data.Cube_API.ReadMetadata/EBA02/JSON-stat/2.0/en` (table last
 * updated 2026-05-01). Dimensions: STATISTIC × Year (TLIST(A1), 2009–2026)
 * × BER Rating (C03440V04149) × Dwelling Type (C03151V03803) × Main Space
 * Heating Fuel (C03442V04151) × Period of Construction (C03441V04150) ×
 * County/Dublin Postal District (C03444V04153). The full cube is too large
 * to fetch, so we use the JSON-RPC endpoint with a dimension filter.
