building light

A flat blue rounded rectangle on a near-black stage becomes a soft natural spotlight in six steps, the way you'd build one in a design tool. For each step a dark settings card appears beside the light, joined to it by a thin line with a blue end dot, and a cursor grabs the field's scrub icon and drags the value with a small overshoot and correction while the light follows live: Layer blur, Progressive, End 40 (the beam softens and widens downward); Layer blur, Uniform, 150 (a glow); Ellipse, FFFFFF, 90 % (a hot spot on the floor); Layer blur, Progressive, Start 100 (the spot spreads, light spills); Layer blur, Uniform, 250 (a deep blue haze, the beam becomes a cone with a bright core); Noise, 40 % (film grain). Seven step dots track the progress; the result holds, then every effect eases back to the flat shape. The light is a half-resolution canvas with real canvas blur filters and gradient masks, the grain its own canvas in overlay blend; the cards are Geist and Geist Mono. ?rec and window.__render(t) draw any moment for frame-exact video export, and reduced motion gets one still.
