/* Part trace: the BOM row hooks, the right-click menu and the player dialog.
   Loaded by index.html (the Review screen) and by trace-player-demo.html.

   Everything is prefixed tp- and nothing here relies on the host page's reset:
   index.html zeroes every margin and sets border-box globally, the demo page
   does neither, and the player has to look the same on both.

   Colours are index.html's own: the grey page ground (#F3F4F6), the slate
   sidebar (#1E293B) for the step list, and the .trace-badge-* palette for the
   rule actions, repeated below as .tp-badge-* because the demo page does not
   carry index.html's stylesheet. */
