## Methodology

Projected from the live listing datasheets using the tenant’s “Per seat, and is there a floor or a ceiling?” axis. Membership requires a sourced yes; partial and unknown answers are reported above but excluded from the ranking. Entries retain the directory’s paid-tier ordering, visibly labelled on every promoted card.
