/* BioStudio AI — Stat Studio.
   One visual system with Clarity's AI tab (clarity/app/chat-workspace.css
   --gpt-*): ChatGPT greys and spacing on White and Black windows, the window
   theme's own colours on tinted ones.

   OS window-colour traps (css/app-color-themes.css), all avoided on purpose:
   - class names never end in -card / -tile / -stat / -panel / -pane / -pill /
     -chip / -btn / -button / -box / -note / -meta / -hint / -sub / -empty /
     -caption, and never contain -tab / -plot / -chart / -figure / -legend /
     sidebar / toolbar / dialog / dropdown / popover / modal;
   - the two forced-text rules skip `.stx *`, and `.stx` is authored colour
     content (js/platform/app-color-theme.js);
   - fields carry .stx-field / .stx-plain and win back below. */
