Workaround: embed SVG as data URI in `html.Img` elements using `urllib.parse.quote()`. Limitation: `stroke="currentColor"` doesn't inherit from parent CSS, so icons appear in their default SVG color (black) rather than inheriting the sidebar item color. This is cosmetic and acceptable for now. +- Dash serves a minimal HTML shell; all React components render client-side.
