  Denwatech redesign theme layer — tokens match the developer spec
  (Page Spec: HOME, Section 0 — Global Design System).
  Loaded alongside the legacy template CSS (main.css + plugins) so pages
  that haven't been rebuilt yet keep working. Everything here is scoped
  under a "dw-" prefix so it never collides with old template classes.
  No content in this file is DB/admin-panel driven — the site is static.
