/* props.css - the properties panel (#right-panel), owned by props.js.

   Quiet and precise, dense like a pro tool: a header with the panel title, sections separated
   by hairlines, compact two-column rows (label | control) and numbers in mono. The highlighter
   is never used here (it marks the active mode and tool only); pressed toggles use the ink
   tint, and proof red appears only on Delete and redaction. The shell (app.js) owns the
   panel's size and drawer behaviour; this file styles what is inside it. */
