/**
 * Creawith Revision 110
 * Scope: recommendation-feed states, toolbar mount, universe boundary, and sticky header.
 * Existing home-feed and work-card styles remain the sole owners of grid and card appearance.
 *
 * Design read: preserved community gallery with a quiet, low-chrome loading layer.
 * Dials: DESIGN_VARIANCE 7, MOTION_INTENSITY 5, VISUAL_DENSITY 4.
 * Shape rule: new controls use 12px corners; existing card geometry is inherited.
 * Layer scale: sticky header 30; no other layer is introduced.
