- single design-token block (colors/spacing/radii/type) drives every chrome surface
- tab strip and toolbar merged into one cohesive surface instead of stacked bars
- inline SVG icons replace text glyphs (back/forward/reload, ads, downloads, properties, new tab, KIR pin, close) with tooltips and aria labels
- tabs: rounded shapes, favicon letter badges, masked title truncation, hover close/pin, clear active/hover/suspended states
- URL bar: pill with site-info indicator (HTTPS lock / HTTP warning / internal page), focus glow, select-all on focus
- right-side controls grouped into one capsule; adblock and downloads show clear on/off states
- downloads panel and permission prompt restyled; properties page matches the same tokens
- behavior unchanged: all existing buttons, IPC commands and shortcuts (Ctrl+L/T/W, F5, Ctrl+R) work as before
