/* =============================================================================
   ISOTOPE Hadron — Fluidics Studio (#fluidics): the frame
   A sibling of Secant Studio and Quanta Studio: the root is an .nx-root, so the canvas family's components (toolbar,
   KPI strip, buttons, segmented switches, chips, pills, checks, tables, popovers) apply as they are. This sheet adds
   only what the studio has of its own: the frame layout (bar, banners, KPIs, scenario rail | stage | inspector,
   wiring console), the delta, origin and status marks (never colour alone: a glyph and a word too), dialogs and menus
   (which live outside the root, on <body>), and the narrow layouts down to 320 px. The lens renderers have their own
   sheet (fluidics_canvas.css, prefix flc-). Carbon tokens only; light themes take the 60/70-grade tag colours where
   a status colour is also text.
