   27K Publishing — Shared Tool Shell
   --------------------------------------------------------------------------
   Styles the header/footer injected into every OnePage tool page via
   #tool-site-header / #tool-site-footer. Deliberately self-contained:
   it does NOT reference any individual tool's CSS variables, fonts, or
   color tokens (e.g. Craft Price Wizard's --cutmat/--ink/etc.), so it
   renders the same way no matter which tool it's dropped into. All
   selectors are scoped under .tool-shell-* to avoid collisions with a
   tool's own class names.
