<h1>On-screen features</h1>
<p class="tagline">The interactive bits around the forecast table.</p>
<h2>The sky scope</h2>
<p>
The large circular visualisation at the top of the page shows the current sky conditions. The sky
colour smoothly interpolates through a full set of elevation-keyed gradients — from deep pre-dawn
navy through golden sunrise, bright midday blue, warm sunset amber, and back to night — with a sun
disc whose glow radius and intensity scale with the actual shortwave radiation at that moment. It
shows the real current time, not the hour you're browsing in the table, and refreshes automatically
alongside the forecast.
</p>
<h2>Day strip weather and temperatures</h2>
<p>
Each day tab in the date selector shows the day's forecast at a glance: a weather icon representing
the dominant daytime conditions (sun, cloud variants, or precipitation), plus the day's high and low
SunSoak felt temperatures in warm and cool colours. The icon uses the actual daytime solar elevation
and cloud category data, so it reflects the real character of the day rather than a generic symbol.
</p>
<h2>Weather event banners and popups</h2>
<p>
When notable conditions are forecast — a frost, strong winds, fog, or a heat event — a banner appears
above the forecast table with a brief alert. Wind banners classify conditions from Strong Breeze
through to Violent Storm using standard Beaufort categories. Tapping or clicking the event icon opens
a detailed popup explaining what the condition means and what to watch out for. Multiple events can
appear at once.
</p>
<h2>What's Coming — cosmic events almanac</h2>
<p>
A 🔭 panel below the forecast table shows upcoming astronomical events for your location over the
next 90 days: meteor showers, lunar and solar eclipses, planetary conjunctions, and oppositions. Each
entry shows the event name, peak date, a countdown, a short description, and a visibility note where
the event is better from a particular hemisphere or location. When a cosmic event is currently active,
it also appears as a banner above the forecast table alongside the weather alerts.
