/* ─────────────────────────────────────────────────────────────────────────────
   Trade73 public site.

   One stylesheet, no JavaScript, no web fonts. The page is the product's first
   impression and the thing crawlers read, so it renders from HTML and CSS
   alone — nothing here waits on a script, and there is no layout shift to
   measure because nothing arrives late.

   The palette is lifted from the application's landing page so the two do not
   read as different products.
