Use when you want to (1) brand an Auth0 tenant's Universal Login to match a website or brand assets (colors, logo, fonts, page layout, text); (2) manually update one or more branding values (logos, colors, fonts, borders, backgrounds, text strings, or the page template) without extraction; (3) rewrite login text to match a voice and tone; (4) reset branding to Auth0 defaults; or (5) check whether a tenant is set up for branding to take effect end-to-end. Does not cover Advanced Customizations for Universal Login (ACUL); use the `acul-screen-generator` skill for that.
