<style>blocks with a configurable background (default: cool blue tint). - Highlights the HTML markup area with a configurable background (default: subtle dark tint).
- Colors are reflected in the overview ruler (the minimap scrollbar gutter) for quick orientation.
- Works automatically on any open
.sveltefile — no commands needed.
