"""Parser for Budget Mini Storage (facility 001918).

This facility's website (budgetstoragetx.com) is a Duda-built brochure site
that does not list unit sizes or prices online. The storage-units page says
"Call us for specifications regarding our storage units!" and directs visitors
to call 512-847-1533. The parser returns zero units with a diagnostic warning
so the pipeline can classify this as a no_pricing facility.
