Lock the Editor to Theme Colors and Font Sizes
Removes the custom color picker, default palettes and custom font sizes from the block editor, so editors can only use your theme's brand styles.
Snippet Library
Disable Features snippets for WordPress
Snippets that switch off WordPress features you do not use: comments, the block editor, RSS feeds, automatic updates, attachment pages and more. One snippet per feature, so you turn off exactly what you want and nothing else.
Stop WordPress Serving Its Logo as favicon.ico
When no Site Icon is set, WordPress answers /favicon.ico with its own logo. This returns a plain 404 instead, so your tab never shows the WordPress logo.
