/**
 * SchemaToolbar — floating toolbar rendered on top of the Schema Builder
 * canvas. Provides Tidy-Up / Fit-View / Export-PNG buttons and a fuzzy entity
 * search input.
 *
 * Reference: `docs/plans/20260501-universal-wysiwyg-schema-ux-v1.00W.md` §3.6
 * items 6 (minimap + zoom-to-fit + search) and 8 (PNG export).
 *
 * Positioned `absolute top-2 left-2 z-10` inside the canvas container so it
 * stays glued to the canvas on resize without introducing any new layout
 * primitive.
