/* ===========================================================================
   GUIAS — shared stylesheet for the resource hub and every guide page.

   Built ON TOP of styles.css, never beside it: every colour here resolves to a
   token already defined in that file's :root. If a value is hard-coded below it
   is because it is a one-off tint of an existing token, not a new brand colour.

   WHY THIS FILE EXISTS AT ALL (and why there is no component library):
   tandom.com.br is static HTML with no build step. tandom.ai is Next + React +
   Tailwind + shadcn, which is why shadcn lives there and not here. On a content
   site, consistency comes from a GENERATOR, not from components: every page
   under /guias is rendered by build_guias.py through one template, so drift is
   impossible by construction. Add a guide by writing markdown, not HTML.

   Palette note: the landing page runs periwinkle (--primary) as its accent.
   The hub runs GOLD (--gold1/--gold2), which is the site's warm signature, so
   editorial content reads as a distinct surface from the sales page while
   staying inside the same system.
