presentation-inspect-editor

Build a resolved id set with tag+path and tag+text fallbacks instead of strict id equality, since style patches and drags rewrite target ids. Also make the panel send the full selection array through the apploop-presentation-set-selections postMessage so panel clicks drive the slide.

Marpit scopes front-matter CSS under div.marpit > svg > foreignObject > section, so selectors like section .apploop-el-xxx never match. Use bare class selectors and pair them with inline style attributes on wrapper spans for durability.

Inline elements ignore width, height, and transform as plain inline boxes. Set display: inline-block alongside position absolute for resize or transform for movement so the style patch takes effect.

Synthesize MouseEvent sequences against iframe.contentDocument with view set to the iframe's contentWindow and buttons: 1 for drags. Wait roughly 900ms after clicks and 2500ms after drags before asserting, since selection state arrives via postMessage.

The guide is measuring one grabbed element instead of the selection union rect, so its center Y rarely matches the slide center. Drive guides from currentSelectionRect and evaluate them once after the whole move loop.

Measure the image's natural size in the browser, parse the slide size from deck front matter, and emit Marp w:/h: alt directives only when downscaling is needed. Preserve existing alt tokens when renaming so sizing directives are not wiped.
