/**
 * editor-layout.css — Three-pane dark editor for review.html
 * (Issue 136 + 2026-06-07 redirect — softer, rounder, more "futuristic").
 *
 * Layout: CSS Grid with three columns:
 *   .editor-player     | left, fluid           | the 9:16 video + meta + actions
 *   .editor-transcript | middle, fixed 35rem   | always-visible transcript pane
 *   .editor-tools      | right, --editor-strip-width | vertical icon strip
 *
 * Soft direction:
 *   - Panel radius is --editor-radius (12px), not the 4px data-page lock.
 *   - Subtle indigo-tinted surfaces (#0b0c12 / #14161f / #1c1f2c).
 *   - Drawer is a glassmorphism panel (backdrop-filter blur + accent glow).
 *   - 220ms ease-out for the slide-in instead of the snappy 120ms.
 *
 * Visibility is driven by a single data-active-tool attribute on
 * .editor-shell; each drawer panel declares data-tool="x".
 *
 * Mobile: at <=900px the three columns stack vertically and the drawer
 * becomes a bottom sheet. No JS branch — pure media query.
