   <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.
+    The large circular visualisation at the top of the page shows the 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 shortwave radiation at that moment. It's a live
+    weather simulation, not just a colour wheel: cloud, rain, snow, and haze are all rendered from the
+    forecast, so the scope actually looks overcast, wet, or misty when the weather is. By default it
+    tracks the real current time and refreshes automatically alongside the forecast.

+  <h2>Day-cycle time-lapse</h2>
+  <p>
+    Press the <strong>Day cycle</strong> play button (▶) on the scope to run a 24-hour time-lapse.
+    SunScope drives the scope smoothly through the next 24 hours — roughly 15 simulated minutes per
+    real second, so a full day plays out in about a minute and a half — animating the sky gradients,
+    the sun's rise and fall, and the evolving weather as cloud rolls in, rain starts, or fog lifts. A
+    live clock label shows the simulated time as it plays; press again to stop and snap back to now.
+  </p>
+
+  <h2>The draggable timeline</h2>
+  <p>
+    Below the scope sits a 24-hour <strong>timeline bar</strong>. Its background is a gradient built
+    from the actual per-hour sky colours across the coming day, so the bar itself previews how the sky
+    will shift from dawn to dusk. <strong>Sunrise (↑)</strong> and <strong>sunset (↓)</strong> markers
+    sit at their real times on the bar, with clock ticks at the quarter points. Grab the thumb and
+    scrub to any instant to jump the scope — and the "why it feels like this" breakdown — to that
+    moment, with everything interpolated smoothly between the hourly rows rather than snapping.
