/* App-wide "modern" skin: brings every page after sign-in (and auth, docs, errors) into the
   landing page's design language - Helvetica Now, ink-on-studio-grey neutrals, pill buttons,
   large soft radii, calm shadows, generous whitespace.
   Loaded after app.css, so it works by (1) re-pointing the design tokens and (2) restyling
   components. Semantic colours are kept: green = up/buy/live, red = down/sell/danger.
   Helvetica Now ships in ONE weight per face, so nothing here asks for bold (browsers would
   fake it): emphasis uses the Medium display face at weight 400 instead. */
