/* =========================================================
   Conversion Diagnostic — page-specific styles (conversion-diagnostic.html)
   Rebranded from the original standalone "Paid Search Funnel
   Diagnostic" app onto alexd.com's design tokens (tokens.css)
   and shared component conventions (style.css / win-pace.css).
   All original .pd-* class names are kept verbatim since
   js/conversion-diagnostic-app.js targets them directly by
   id/class — only color, type, radius, and a few structural
   rules change here.

   Color mapping (brand-color rule: full-opacity red/blue/yellow
   or greys/white/black only, never tinted):
     good     -> var(--blue) text/dot
     warning  -> var(--yellow) dot, but TEXT stays ink (yellow text on
                 white fails contrast)
     critical -> var(--red) text/dot
   Status labels (top diagnosis badge, data-quality chip, per-card
   quality tag) are styled like the site's .eyebrow component — plain
   colored uppercase text with a small dot, no pill/fill — since
   they're labels, not buttons, and shouldn't compete visually with
   the real CTA buttons.
   --pd-brand (blue) drives the app's "inner workings" — progress
   stepper, selected window button, auto-suggested tag, focus rings.
   Only the primary/secondary CTA buttons are deliberately monochrome
   (solid black / unfilled black outline) so they read as actions,
   distinct from the brand-colored data and status elements around them.
   The three funnel-layer categories use all three real brand colors as
   a legend, each fully distinct: Search Demand -> yellow, Google Ads
   -> red, Landing Page -> blue.
