Viktor Barzin 5d16a18cf4 ADR-0017: document trunk traffic semantics + ASCII topology 
While reviewing the single-switch design Viktor asked whether both the
home LAN and the camera VLAN 'go via pfSense which forwards upstream' -
a natural misreading a future reader would repeat. Added a section
spelling out the vmbr0 fork: untagged home LAN is L2-bridged past
pfSense (gateway stays the AX6000, rack outage does not affect it, OOB
via 4G survives), while tagged-30 can only land on the dCCTV interface,
making a pfSense bypass impossible by construction. Includes a compact
ASCII topology for terminal readers alongside the SVG.
