* feat(studio): apply a style to a run of characters Styling text in a composition cannot be done by wrapping a DOM range in a span. That is three lines, and then every interesting case is a special case: recolouring nests spans that shadow each other, removing a style cannot reach the ancestor that set it, and styling across an existing run's boundary has to split it. Each fix is a new branch and the branches interact. So the element is read into a flat list of styled runs, the style is applied to a span of characters in that list, and the element is rebuilt from it. Replacing, removing, splitting and merging stop being cases: the rebuild emits one span per distinct run and cannot nest or duplicate, whatever was there before. Selection offsets count UTF-16 units, so a boundary can land between the halves of an emoji; the applied range widens to whole characters. A colour an ancestor overpaints is mirrored into the fill, because a colour that does not paint reads to the user as a colour that did not save. The toolbar that drives this arrives with the editor in the next change. * fix(studio): harden inline text styling boundaries * fix(studio): align inline styling with persistence * test(studio): pin inline identity delimiters
