// Reading order inside UTCIForecast():
// 1. STATE (useState calls) — bits that change on interaction
// 2. EFFECTS (useEffect calls) — runs on search / location change
// 3. COMPUTATION (hourlyRows, days, …) — API data → display rows
// 4. JSX RETURN (the big html`...`) — actual page markup

<h2 class="utci-about-heading">What is SunScope?</h2>
<p class="utci-about-text">
SunScope is a free hourly weather forecast built around <strong>felt temperature</strong>,
not just air temperature. It uses the <strong>Universal Thermal Climate Index (UTCI)</strong>
the biometeorological standard used in heat-health warning systems worldwide as its
foundation, combining air temperature, humidity, wind, and solar radiation into a single
honest number. Then it goes further. Our <strong>SunSoak</strong> index layers three extra
dimensions on top: a rain and snow penalty so wet, windy days read as cold as they feel;
an <strong>environment modifier</strong> that adjusts the solar load for where you actually
are forest canopy, alpine altitude, lakeside glare, shaded riverbank, desert ground heat;
and the full radiant heat absorbed from surrounding surfaces. One number that honestly
answers: <em>what will my body actually feel out there?</em>
</p>
<p class="utci-about-text">
Beyond SunSoak, SunScope calculates <strong>vehicle cabin heat</strong> (choose your
vehicle type; toggle windows open), <strong>indoor temperature</strong> (seven building
types including office blocks; managed heatwave mode), <strong>urban concrete surface
temperature</strong>, <strong>UV index and sunburn time</strong> by skin type, and
<strong>soil temperature and moisture</strong> for farming and motorhome use. Switch
profiles Places, Activities, Work to see the data that matters for your situation,
or go Custom and build your own view.

<div class="utci-footer">
<em>Reading the table.</em> SunSoak is the number to watch — it reflects everything your body
actually experiences, not just what the thermometer says. A large gap between SunSoak and Air
temperature means solar radiation is doing significant work on your body. On clear sunny days
that gap can exceed 10 °C even at modest air temperatures. The environment modifier in the
SunSoak dropdown adjusts the solar load for your surroundings switch it to match where you are
for the most accurate reading.
