/* tools-embed.css — SELF-CONTAINED styling for a tool embedded inside an article.
   Scoped entirely under .lab-embed (no dependency on the .lab page theme). Uses
   translucent overlays over the host site's own surface + inherits the site's text
   colour, so the block reads as an intentional part of the article on the dark
   casino themes. Chart colours are a fixed, legible data palette. */
