/* DeepECG-Bench — visual language matched to ECGBench (vajira.info/ECGBench).
 *
 * The two sites are siblings (ECGBench catalogues the datasets, this site the models), so
 * they share a design: dark ground, blue accent, centred hero with radial glow and
 * gradient-filled title, rounded cards, uppercase micro-labels, Inter-first type.
 *
 * ECGBench ships dark only; we keep a light theme on the toggle, so every token is declared
 * twice and NOTHING outside these blocks may contain a literal hex —
 * tools/tests/test_style.py enforces that, and the contrast of both palettes.
