/* AutomationFlex marketing site.
   No framework, no build step. Fonts are the only external request.

   Nothing here is locked in. Colours, type and spacing are a first pass meant
   to look considered rather than default, ahead of a proper design later.
   Deep navy with a warm accent on purpose: every automation company on the
   internet ships the same blue gradient, and the audience is roofers. */
