/* stats.css — styling for the "What the numbers say" analytics view (js/views/stats.js).
   Everything is prefixed .st- to avoid collisions with the rest of the app. No hardcoded colours:
   every colour reference is one of the CSS variables defined in css/app.css, so this view inherits
   both the dark and light theme automatically. No chart library, no canvas — bars are plain divs. */
