/* ==========================================================================
   VirtuITS — static stylesheet
   Hand-written port of the Tailwind design tokens in src/index.css.

   Note on colour naming: the original Tailwind config aliased `teal` to the
   orange token, so every `text-teal` / `bg-teal` in the React source actually
   renders orange. That misnomer is not carried over here — the accent colour
   is simply called `--accent`.

   Every font-size below is paired with the line-height Tailwind's `text-*`
   scale applies, since those two always travel together:
     xs .75/1rem · sm .875/1.25rem · base 1/1.5rem · lg 1.125/1.75rem
     xl 1.25/1.75rem · 2xl 1.5/2rem · 3xl 1.875/2.25rem · 4xl 2.25/2.5rem
     5xl 3rem/1 · 6xl 3.75rem/1   (relaxed 1.625 · snug 1.375 · tight 1.25)

   Breakpoints match Tailwind exactly: sm 640, md 768, lg 1024, xl 1280.
