#1573's five formatted block messages carried {}/{name} in every locale, so the catalog never filled them and the UI printed the brace text; they use the __ocs_fmt_0__ marker now. The Options collapse arrow, the library up button and the folder picker are SVG icons instead of glyph text, and the Details header drops its sort glyph. The contrast test follows the cards to the weak surface pair and the palette test closes with BLOCKSPALETTECLOSE, since BLOCKSPALETTE now only opens.
