Show HN: CrossX – iOS/macOS App to Convert web/X articles to ePub for e-reader (github.com)

Native iOS/iPadOS/macOS app: paste URL (or Safari share sheet), convert webpage or X thread (via fxtwitter) to clean EPUB 2.0, push directly to Xteink X4 over WiFi hotspot. No cloud, no accounts. Supports stock firmware (192.168.3.3) + CrossPoint custom (crosspoint.local / 192.168.4.1) with auto/mDNS detect.

Early/WIP but daily-driver usable for me. Feedback welcome on parsing quality, connections, or next steps (images in EPUB, batch, etc.).
