/*
 * CE Scroll Engine styles
 * Design system for the motion sections, driven by Core Framework variables.
 *
 * Rules:
 * - Color, spacing, radius, type all reference Core Framework variables.
 * - Decorative values with no CF equivalent are declared here as scoped
 *   tokens on .ce-scroll so there are no raw literals in the rules below.
 * - Adapt the LOOK by changing Core Framework variables, not this file.
