What problem does it solve? Designers and developers often misuse side panels by making them modal, hiding critical content, or inventing unsupported variants like sizes and sides. This Skill defines exactly when a Recursica panel is justified versus a modal, page, or toast, and enforces its accessibility and layout rules. ## Core Features & Use Cases - Decision guidance: Distinguishes panels from modals, toasts, pages, and cards with a clear use/when-not-to-use table. - Accessibility rules: Covers focus management, Escape dismissal, focus return, screen-reader naming, and the prohibition on trapping focus in non-modal panels. - Adapter defect workaround: Documents the Mantine Drawer default overrides (withOverlay, closeOnClickOutside, trapFocus, lockScroll) needed to achieve non-modal behavior. - Use Case: When adding a filter panel beside a data table, use this Skill to confirm the panel stays non-modal, stacks form labels, announces filter results to screen readers, and avoids horizontal scrolling. ## Quick Start Ask the agent to review or build a Recursica panel for showing filters beside a page without blocking it.
