OFFLINE / ISOLATED NETWORK GUIDE
================================

This app works fully WITHOUT internet. The server PC and guest phones
only need to talk to each other on the same WiFi/LAN.

WHAT THE APP DOES (software)
----------------------------
- All pages, fonts, and scripts are bundled inside wedding-upload.exe
- No calls to Google, CDNs, or the public internet
- Uploads go only to this PC (local disk)
- Security headers block the browser from loading external websites

WHAT THE APP CANNOT DO (hardware/router)
----------------------------------------
The app cannot stop guests from using the internet if your WiFi router
still gives them access to the web. That is controlled by the ROUTER.

To block guest internet (recommended for focused uploads):

Option A — Guest WiFi with no internet (best)
  - Create a guest SSID on your router
  - Do NOT connect that guest network to the internet/WAN
  - Connect only this Windows PC to that network (or PC on LAN + guests on guest SSID with AP isolation)

Option B — Router "client isolation" + no gateway
  - Guest network: disable "Allow guests to access WAN/internet"
  - Enable AP/client isolation if available

Option C — Phone hotspot (small events)
  - Use a second phone or portable router as hotspot
  - Do NOT enable mobile data on the hotspot device
  - Only this PC and guests connect — no internet path

WILL LACK OF INTERNET CRASH OR SLOW THE APP?
--------------------------------------------
No. After these updates:
- The app does not wait for internet
- Fonts load from the app itself (not Google)
- Upload speed depends only on WiFi + disk, not the web

VENUE PC TIP
------------
- You may unplug Ethernet / disable WiFi internet on the SERVER PC
  if you only need guests to reach http://YOUR-PC-IP/
- Keep the LAN/WiFi that guests use — just remove WAN if you want zero web access
