/* Pinned review comments (UX Pack F5b, restyled F5c) — pins, docked panel,
   composer, link modal. The panel look is ported from the CRM design-reviewer
   (.dr-rev-panel / .dr-feedback-card geometry) recolored with --pb-* tokens.
   SELF-SUFFICIENT BY DESIGN: /review.html loads tokens.css, builder.css,
   toast.css, this file and review.css — NOT property-panel.css, where the
   drawer-shell classes (.pb-spi-drawer*) are styled. They are therefore
   restyled here from scratch, and no rule below may depend on a sheet the
   review page does not load. */

/* Comment mode: every click pins feedback instead of editing or navigating,
   so nothing on the canvas may advertise drag/pointer/not-allowed. This is
   the PARENT half only — it covers the iframe element and the glass overlay
   (a sibling of the iframe inside .pb-iframe-wrap). A cursor set on the
   <iframe> element never reaches the document INSIDE it, so the other half
   lives in css-assembler.js's EDITING_CSS, keyed on a body class the bridge
   sets. Same two-sided treatment as AI pick mode (builder.css).

   NO `!important`, unlike pick mode's copy of this rule: that one lives in
   builder.css, which loads BEFORE glass-overlay.css, so it had to shout to win.
   comments.css loads last (index.html), so equal specificity already wins on
   source order — verified in a browser against the overlay's own cursors. */
