/* Cody Image Converter — styles
   Design concept: a photo darkroom's workbench/ledger. Deep ink
   background, one warm "enlarger bulb" amber accent used only for
   primary actions and the drop target, and tabular data (sizes,
   dimensions, percentages) set in monospace so numbers line up like
   entries in a ledger. No external fonts or CDNs — system font
   stacks only, so the page has zero network dependencies beyond its
   own files. */
