   verdict banner, check rows, badges, raw JSON panel, toasts, the unified loader and the history panel. */

/* ---------- page frame ----------
   A tool page fills the content area, capped only on very wide screens; a page's own stylesheet (loaded after this
   file by includes/layout.php) can change the cap, e.g. `.rb-page { max-width: none; }` for a full-width workbench.
   Inside, single-line fields and hint text keep a readable measure so a simple form does not stretch across the
   screen, while result grids, tables and cards use the whole width. */
