Module auth_backdrop 

Quiet current: the shared authentication artwork for the lock and greeter.

Four curved sheets catch a narrow band of light. Their folds move slowly, leaving the clock and credentials on calm ground. Everything is vector geometry and theme color; no image, texture, shader, or frame history is needed. Callers own the clock and request frames only while visible.

Functions

draw

Paint an opaque authentication backdrop inside bounds.

needs_animation

Whether the caller should schedule animation frames for this backdrop.
