/* Design tokens ---------------------------------------------------------
   Field Notes: kraft-paper chassis, ink text, one rust accent thread
   running through every interactive/live element — matches the homepage
   and every other Thermalsock Labs app. The scope canvas itself is
   separately themeable (see js/themes.js — Field Notes is the default
   canvas theme too, with CRT/Modern Lab/Aurora/Woven still selectable),
   but the chrome around it (topbar, panels, buttons) always stays in
   this one house style regardless of which canvas theme is active.
   Type: Space Grotesk (display) + system sans (chrome labels) + IBM-Plex-style
   mono for dense numeric alignment, matching the homepage's type system.
   Corner radii follow the shared scale: 10px windows/panels, 6px
   controls/buttons, fully-rounded pills for status/nav badges.
