v0.4.2 ships the real marketplace icon and gallery banner.
The new icon (resources/icon.png) replaces the placeholder grayscale glyph: interlocking arcs converging through a luminous core, with four sync targets at the cardinal points. Gallery banner is dark with theme=dark for clean rendering on both VS Code Marketplace and Open VSX.
No functional changes from v0.4.1.
