Pixel Scroll — Scroll-driven pixel transition

The component supports two reveal approaches:

• Colors mode: transitions from one color state to another, with optional accent pixels.

• Two-layer mode: transitions from Layer A to Layer B (image-to-image style transition).

Main controls and functionality:

• Pixel Size and Gap: define the block size and spacing.

• End At: sets when the transition finishes within the scroll range.

• Direction: controls flow (top-bottom, bottom-top, left-right, right-left, center-out, center-in).

• Pattern: changes threshold distribution (random, checker, diagonal, wave, spiral, radial).

• Pattern Intensity: controls how strongly the selected pattern affects transition timing.

• Easing: shapes transition timing (linear, ease-in, ease-out, ease-in-out, expo-out).

• Accent Share + 4 Accent Colors: adds controlled variation inside the transition band.
