Files to create: 063-desert-dunes.html + 063-desert-dunes.txt — Desert dunes with heat haze and wind-blown sand under a low sun. Palette: ochre, rust, warm amber sky. Signature: layered dune silhouettes with parallax, heat-haze via animated blur/distortion, drifting sand particles, glowing sun.

DESIGN DESCRIPTION
A dusk desert built from a warm amber-to-rust sky gradient that deepens into ochre and sepia at the ground. A large, copper-thick sun sits low on the right, casting a broad radial glow and a soft halo, its disc edged with a warm shadow blur. Five stacked dune ridges recede from deep sepia in the foreground to a hazy warm ochre in the distance, each drawn as a smooth quadratic curve with a sunlit rim-light along its crest. Over the whole scene a separate screen-blended "haze" canvas rises with drifting warm shimmer blooms that wobble upward — the signature heat distortion — while wind-blown sand grains comb horizontally across the ridgelines and drift with the breeze. An editorial overlay in italic serif, tabular temperature/wind/sun readouts and a warm vignette complete the composition.

MAJOR VISUAL TECHNIQUES
- Five layered dune silhouettes drawn as smooth quadratic-curve ridges, each with a distinct ochre→rust gradient and a sunlit rim-light stroke.
- Parallax: the sun's horizontal position (and pointer drag) shifts the dune layers at different rates to imply depth.
- Heat haze on a dedicated screen-blended canvas — warm radial shimmer blooms that rise, wobble on a sine and recycle, simulating animated distortion.
- A glowing low sun: radial-gradient disc with an added shadow-blur halo and a broad multi-stop glow gradient.
- Wind-blown sand: hundreds of small particles streaming horizontally, resetting off-screen, speeding up with pointer drag.
- Warm amber/rust/ochre palette with a radial vignette and tabular-nums editorial legend.
- Pointer-driven sun tracking that also nudges the sand wind, with reduced-motion slowdown.

INTENDED INTERACTION MODEL
Passive: the sun gently bobs, heat shimmer rises and sand streams across the dunes on its own. Move the pointer left-to-right to shift the sun across the sky, which retints the glow and pushes the dune parallax; the sand picks up speed in response. Press and hold (drag) to stiffen the wind and comb the sand harder. Everything slows but keeps moving under prefers-reduced-motion.
