SVG vs ICO Icons
SVG is the future; ICO is the floor. Ship both.

Why SVG wins on modern browsers
One file, infinitely scalable, supports dark-mode media queries. File size is typically under 2KB.
Why ICO is still essential
Older browsers, Windows shortcuts, and some embedders only read .ico. Skipping it produces a broken icon for ~5% of users.
Use both together
Link favicon.ico first as a universal fallback, then a <link rel="icon" type="image/svg+xml"> on top for browsers that support it.
