/* profit-analyzer/assets/profit-analyzer.css
   Owner landing page for the Profit Analyzer. Loads after tool.css and
   shared/styles/calculator.css, so page chrome, the hero, the banner and the
   article come from there. This holds only the upload panel, the sample
   dashboard preview and the analysis overlay, behind the .pa- prefix.
   Colours are custom-colors.css variables. */
