/**
 * DVR command menu (Select Day / Theme / Display / Debug / About) and its
 * submenus. Menu-item icons are replaced with the app's existing inline-SVG
 * language (they were emoji — the ONE inconsistency in the icon system that
 * was safe to fix: these five are static markup, not server-driven like the
 * sensor-list glyphs). JS only toggles .visible/.active classes here; the
 * open/close/hover mechanics are untouched.
