Upgrades Browse cards from flat gradient swatches to themed SVG graph thumbnails + palette chip rows, sourced from real runtime tokens. Grid widens to 2-3 columns. Active sub-nav tab gains a 2px accent underline.
v102.0.22026-06-02
·ThemeGraphThumb: shared 12-node/14-edge SVG constellation, same layout per card — users compare color not shape; bg/edge/node colors from real runtime tokens (app.background, panelBackground, graph.edgeDefault, graph.nodeColorScale)
·Glow treatment: blurred circle at 0.35 opacity behind each solid node (per prototype spec)
·5-chip palette row from nodeColorScale[0..4] using .lw-palette-row / .lw-palette-chip CSS (flex, 14px, inset shadow, hover lift)
·Grid: minmax(150px) → minmax(240px), giving 2-3 columns at panel width
