   - Fully scoped under `.epf-scope` (no global leakage).
   - All colors / speeds are CSS custom properties, overridable at runtime
     from the CONFIG object in `core/static/core/js/project-flow.js`.
   - Responsive via CSS container queries (adapts to whatever column it is
     placed in, independent of the viewport).
   - RTL + LTR via CSS logical properties; follows the page `dir`.
   - Honors `prefers-reduced-motion: reduce` (static, readable, no loops).
