/* ihm-reports core/v1 theme. The AdsMatrix demo's look (dark first) with a designed light twin.
   Frozen once a brand pins v1: changes that alter an existing brand's look go in core/v2.
   Series colors are the dataviz reference palette, validated (scripts/validate_palette.js) on both surfaces:
   1 blue = this period / the store, 2 orange = Meta, 3 aqua = Google, 4 yellow, 5 magenta, 6 violet; compare = gray. */
