Improved the dark theme for the File → Open picker: uniform dialog background, restored file preview thumbnails, rounded corners on cards and the search field, and correctly styled list/grid toggle buttons. Menus and popups now keep a consistent background over the Sheets grid.

• New: tabs that were already open before installing now reload
automatically — no more stuck light pages
• Fixed: printing a document no longer produces a dark or blank
printout — print output is clean and light again
• Fixed: text cursor was nearly invisible on dark pages — now a
white-core I-beam
• Darkened the Google app bar (grid/popup) on Docs, Sheets & Slides
• Share dialog and toolbar menus now fully themed
• Various stability and compatibility improvements (incl. Safari)
