   10PM Curfew — shared design system for tools.10pmcurfew.com
   ---------------------------------------------------------------------------
   Tokens and component specs are lifted from analytics.10pmcurfew.com
   (src/app/globals.css) so the two properties read as one product. If a token
   changes there, change it here too — the two files are meant to stay twins.

   Served at /shared/tpm.css. Every page links it, then adds its own tool CSS.
