Building on #412 #608 PRs #870 #1179 #1180 towards a Captive Portal understandable by almost all:

• http://iiab-server.lan/home/ is not acceptable in the field; it needs to show http://box/* or http://box.lan/* per custom setting in local_vars.yml
• Intermediary splash page needs:
  • UX: Captive Portal: The title/text of the page is not centered on the screen [macOS] #1784 UX: Captive Portal: The title/text of the page is not centered on the screen
  • Larger fonts
  • Very crisp/concise/colorful instructions in the most simple English possible (for non-native speakers; ALL users want this disruptive interface minimized!)
  • Implement auto-redirect from intermediary splash page after 10-seconds, per @tim-moody's recommendation, ideally with Javascript countdown (1 in ~10 users want to read instructions)
