HeroTerminal was a single 367-line component doing three separate jobs:
simulating the transfer queue, holding the per-search result sets, and
rendering. It is now useTransfers, useResults and useHeroDemo behind a
presentational component. The dead shellRef went with it.
The home, docs and install pages each returned one long JSX block; every
section is now a named component, so the page body reads as an outline.
The prerendered HTML is byte-identical for all five pages, and the extracted
transfer reducer matches the original over 200 ticks.
