🟡 Stroke-based favicon may be clipped because stroke extends beyond the SVG viewBox bounds (packages/local-explorer-ui/public/favicon.svg:1-2)

The favicon SVG was changed from a filled path to an outlined path by setting stroke-width="3" and fill="none" on the root <svg>.

Because SVG strokes are centered on the path, a 3px stroke adds ~1.5px of geometry outside the original path bounds. The path includes coordinates on the edges of the viewBox (e.g. it reaches x=0/y=0), so the stroke can render outside the viewBox="0 0 66 30" and get clipped during rasterization (common for favicons).

Actual: parts of the outline can appear cut off at the top/left/bottom edges in some browsers/icon generators.
Expected: the full outline should remain visible.

Where this happens

packages/local-explorer-ui/public/favicon.svg:1-2

<svg ... viewBox="0 0 66 30" stroke-width="3" fill="none" ...>
  <path d="... 0 28.133 ... 35.367 0 ..." />
</svg>

Recommendation: Increase the viewBox padding (e.g. viewBox="-2 -2 70 34") and/or add overflow="visible", or reduce stroke-width so the outline doesn’t clip when rasterized for favicon sizes.
