   RESPONSIVE SYSTEM — Boarderless
   Breakpoints (device-width, not pixel-count):
     xs  : < 400px   — small phones (SE, older Androids)
     sm  : 400–600px — standard phones (iPhone 14, Pixel)
     md  : 600–900px — large phones, phablets, portrait tablet
     lg  : 900–1400px — landscape tablet, small laptop
     xl  : > 1400px  — large desktop, 4K monitors
   Strategy:
     - Base styles = "sm" (the modal center of gravity)
     - xs   = shrink everything
     - md+  = grow and re-position panels
     - lg+  = full desktop layout
     - xl   = spacious desktop, larger hit-targets
   Collision avoidance:
     Panels (edit-ui, stack-ui, color-panel, font-picker, layout-picker)
     share a right-side column on desktop and move to bottom-anchored
     sheets on mobile. JS handles runtime conflict resolution when
     multiple panels are simultaneously visible (see initPanelCollision).
