/* ==========================================================================
   ETON DSP Release Platform — visual system (ETON Control Center parity)
   Mirrors the desktop app's design language: warm radial-dark background,
   flat orange accent (#ff8451), neutral #1a/#1f/#22 surfaces, Futura PT,
   ghost controls that light up orange when active, soft layered elevation.
   Tokens + values taken from the GUI's shared/brand/brand.css + eton.css.
   Every selector from the previous stylesheet is preserved.
