Custom CSS, favicon, and per-page tweaks

For anything the themes and accent colors do not cover, each page and the global settings accept custom CSS.

Per-page custom styles

The Custom Scripts & Styles box on the editor has a Custom Styles field. Add CSS there without <style> tags, and it applies to that page only.

Site-wide custom CSS

Under Settings -> Scripts, the Custom CSS field applies to every MyLink page.

Custom favicon

Set a per-page favicon in the Meta box, or a global one under Settings -> General, so the browser tab carries your icon.
