Proofing Gallery 0.6.0

• redesign public galleries as immersive, mobile-first presentations with
  configurable title visibility, photo count, title sizing, and local modern or
  editorial typefaces
• add minimal, compact, and cinematic openers plus an immediate desktop and
  phone live preview for unpublished design changes
• migrate existing galleries to the new modern presentation defaults while
  retaining validated settings compatibility
• keep every photo reachable in narrow one-column galleries with corrected
  window virtualization, resize measurement, and independent pagination
• reshape owner culling around a viewport-bound, virtualized Lightroom-style
  filmstrip that adapts between the right side and bottom placement
• persist each photographer's filmstrip preference across devices and add
  focused previous/next navigation with automatic active-thumbnail tracking
