Thermal palette stops in order from coldest to hottest (2-6 hex colors). The first color is the chilly background tone, the last is the white-hot core; adjacent stops blend smoothly, so pick a hue path that stays saturated (blue→purple→red→orange→cream) rather than jumping across the color wheel.

The void color beneath the coldest zones — the absolute-zero backdrop the heat field fades into. Keep it near-black and slightly tinted toward the first palette stop for a seamless cold falloff.

Backdrop opacity. 1 = opaque thermal scene; 0 = cold zones become fully transparent so glowing heat islands float over the host page section; mid values give a translucent haze.

Global evolution rate. Higher = churning, urgent, lava-lamp energy; lower = glacial, expensive-looking thermal drift. Stay at or below the default for premium hero backgrounds.

Zoom of the thermal field. Higher = many smaller heat cells and busier texture (good for small cards); lower = one or two vast continental heat masses (good for wide heroes).

Number of pulsing hot cores that bloom white-hot and fade on independent slow cycles. Higher = more focal flares competing for attention; 0 = pure ambient field with no blooms.

Intensity of the hotspot blooms. Higher = dramatic white-hot suns with wide halos that dominate the frame; lower = subtle warm embers; 0 silences the blooms entirely.

Directional drift strength. Higher = the whole field visibly streams diagonally like heat carried on a breeze; 0 = the field churns in place with no net movement.

Separation between cold and hot regions. Higher = punchy, high-drama islands of heat against deep cold voids; lower = a gentle, even warmth across the whole frame.

Density of the faint topographic isoline rings traced around heat levels. Higher = tighter, more technical instrument-readout rings; lower = a few broad elevation lines; 0 = none for a perfectly smooth plasma look.

Cursor heat strength. The pointer presses a soft thermal bloom into the field — a tight white-hot core with a wide halo that the palette, isoline contours, and emissive lift all wrap naturally, like a thumb on a thermal camera. It blooms while the cursor moves and cools back to the ambient field within a couple of seconds at rest. 0 disables the interaction entirely.
