Three fixes to the Chrome extension, all with the same cause: the overlay's own stylesheet was being overruled inside its shadow root, so the toolbar and every panel drew in whatever the browser fell back to rather than what MarkLayer asked for.
Fixed
The toolbar and panels use MarkLayer's type again. On every site, any part of the overlay that did not pin the typeface itself — the tooltips, the comment box, the priority picker, the text tool — rendered in the browser's default serif. A comment you were part-way through typing looked nothing like the one beside it. Every surface now shares one type baseline that the annotated page cannot reach into and change.
Dark mode follows your system again. With the theme set to follow the system, a dark desktop still got the light overlay: a white toolbar and a white comment box parked on top of a dark site. Picking Dark by hand had always worked; the automatic option never did. It does now, and the ink follows the surface, so text stays readable either way.
The overlay stays put on long pages. The overlay's own root was laid out against the document instead of the viewport. Layers that pin themselves were unaffected, which is why drawing held its place, but anything positioned against that root — the menus and popovers that open from the toolbar — carried the page's scroll position as an error. It is anchored to the viewport now, and the empty space around the toolbar passes clicks through to the page as it was meant to.
