/* Theme for inlined visualization SVGs (rendered under .dt-svg-root).
   The codegen prompt (rules_svg) emits these pre-built classes instead of
   hard-coded fills, so figures follow the app's light/dark theme and font:
     text:        .t (14px), .th (14px/500), .ts (12px muted)
     neutral:     .box (container), .arr (arrow), .leader (dashed leader)
     interactive: .node (hover), [data-prompt] (clickable)
     color ramps: .c-{gray,blue,teal,coral,pink,purple,green,amber,red}
   Ramp values are Claude's 9-ramp palette. Light = 50 fill / 600 stroke /
   800 text; dark = 800 fill / 200 stroke / 100 text — switched via .dark. */
