chance, and an hourly temperature graph
- Current conditions block redone horizontally (icon left, big temp
+ description + an extras line on the right) instead of stacked
vertically.
- New extras line: "feels like" (apparent_temperature), today's
high/low, and rain chance (precipitation_probability_max) -- each
independently toggleable in settings, all on by default. Switched
from the legacy current_weather=true param to Open-Meteo's current=
param, since that's what exposes apparent_temperature; confirmed
field names/formats live before wiring them in.
- New hourly-today temperature graph (also toggleable): a polyline
across today's 24 hourly points, min/max temps labeled at their
points, a red dot marking the current hour, and hour labels along
the bottom.
- When both the graph and the daily forecast strip are shown, they
split the remaining vertical space; either can be toggled off to
give the other more room, matching how forecast_days already
worked.
