Um, this must be a different RFC 2606 than the one the rest of us have read.
It mentions neither .lan nor .home.

SLAAC lets hosts find their prefix and router and optionally other
stuff like the DNS servers.  See RFC4862.  This is a thoroughly solved problem.
If your router is a captive portal like at a coffee shop and client devices
need to open a web page to log in, see RFC 8910.
