/* ==========================================================================
   Chroma Key Tuner — page-specific styles
   ==========================================================================

   Loaded AFTER product-theme.css. Everything here is a component the theme
   doesn't already provide (monitor overlays, source-row chips, key-color
   swatches, range sliders, toggle switches, a segmented control, the EQ
   grid) — built entirely on product-theme.css's tokens, never hardcoded
   hex, so a future token change here still tracks the canonical file.

   Layout comes from product-theme.css's "AV workbench" section
   (.workbench / .workbench-layout / .monitor / .control-rail /
   .control-section / .status-strip) — this file only adds what that
   pattern doesn't cover.
