/* ==========================================================================
   Swing Flow — stylesheet
   Replaces the inline <style> block in builder.html.

   Design language borrowed from shadcn/ui (MIT), hand-written as plain CSS.
   shadcn components are React + Radix and cannot be dropped into a static
   page, but its *look* is just a token system plus a set of conventions, and
   that ports directly. No Tailwind, no build step, no runtime compiler —
   Tailwind's Play CDN is explicitly development-only.

   Every class name here already exists in builder.html. The markup does not
   change, so this file can be swapped in and reverted freely.
