   DESIGN SYSTEM — modern dark theme (slate + indigo)
   ----------------------------------------------------------------------------
   Every page (including the admin area) styles itself with these variables and
   shared component classes, so the whole product is re-themed from this one
   block. Images pop against the dark surfaces — the norm for pro photo/video
   tools. Legacy variable names are kept so older inline styles still work.
