 * Helio — the support section.
 *
 * An ordinary responsive web page, read on a phone as often as on a desktop. The CSS stays as
 * conservative as its neighbour in samples/dotnet/showcase/streaming-tv — no :has(), no :is(), no
 * nesting, no logical properties, no clamp()/min()/max(), no flex gap — because the two samples
 * share markup and stylesheet patterns and a rule copied across should not stop working on the way.
