Use the Greek lowercase mu glyph as the app's favicon. The SVG
carries a `prefers-color-scheme` media query that flips the path
fill between near-black (light mode) and near-white (dark mode),
so it stays legible against any tab-bar background without an
extra browser hint.
Linked before the existing PNG so browsers that support SVG
favicons (Chrome 80+, Firefox 41+, Safari 9+) pick it up; the PNG
remains as a fallback. `apple-touch-icon` keeps the PNG since iOS
home-screen icons can't be SVG.
