/* Shared cheat-sheet stylesheet for /course/<tool> "Cheat sheet" sections.
   A cheat sheet is a single self-contained HTML page (served from /static and
   shown in an iframe) that links this file and sets its tool's accent:

     <link rel="stylesheet" href="/cheatsheet.css" />
     <style>:root{ --accent:#8b5cf6; --accent2:#a78bfa; }</style>

   Structure: <h1> + .subtitle, then <h2> sections containing .cmd-table /
   .card grids / pre code blocks / .note callouts / .pill badges. One source of
   truth for the look so every tool's cheat sheet is visually consistent. */
