HRRR publishes f21-f48 at 3-hourly intervals in addition to the
hourly f01-f18 we already fetch. This extends the grid_tasks seed
from 19 rows (1 analysis + 18 forecast) to 29 rows (1 analysis +
18 hourly + 10 3-hourly), and bumps the UI forecast window
constant from 18h to 48h so the map timeline and path calculator
forecast chart automatically show the extended horizon.
No Rust logic changes needed — the pipeline is data-driven and
u8 forecast_hour already handles f48.
Replace the markdown-rendered /docs/api page with a structured
LiveView modelled on the Tailwind UI Protocol template — fixed
left sidebar with grouped section nav, hero with metadata dl,
two-column rows where prose sits next to a sticky code sample,
and endpoint cards with color-coded HTTP method tags.
Two issues made docs/api hard to read:
1. The site's custom Markdown parser only recognized `- ` bullets,
so the README's `* ` bullets rendered as a single run-on paragraph
with literal asterisks. Extended the parser (and tests) to accept
the full CommonMark bullet set: `-`, `*`, `+`.
2. The shared .markdown-content container is 88rem wide. Comfortable
for /algo's wide tables but uncomfortable for monospace prose,
which prefers ~80ch. Added a .api-docs modifier class on the
/docs/api page that drops max-width to 60rem, allows table
cells to wrap, and slightly downsizes headings.
