/* BOARDS02 — storyboard packet construction/revision. Same ID8 visual
   language as BOARDS01 (Anton/Inter, dark ground, amber accent) but a
   different layout: the storyboard packet grid is the primary object, not
   a fixed three-column control rig. Board panels are deliberately rough —
   pencil/grayscale placeholder texture, not polished concept art. */
