/* ============================================================================
   author.css — page-scoped layout for the T. Teller author homepage.
   The shared design system (palette, type, texture, components: buttons, cards,
   string-lights, torn-edge, the dog walker, snow canvas, scroll-reveal) lives in
   the shared /assets/css/theme.css. This file only adds page layout on top and
   never redefines a theme token or a shared component class.

   Register: an AUTHOR site, not the book experience. Lighter density, more air,
   the same cold night palette. Restraint is the brand.
