Perfex SaaS Studio — Multi-Tenant SaaS for Perfex CRM: Tenants, Plans, Signup, Billing, Upgrades & Backups

1.0.2 - 2026-10-24 — tenant preview and plan comparison
- What a tenant sees: under Module Features, a preview per plan of the Design Studio page a workspace admin gets
  (upgrade card on your master look, Brand Kit only, or the Studio with its open areas), drawn from the saved values
- Compare Plans: every module feature of your public plans side by side, grouped by module, with prices and intervals;
  one plan at a time on phones
- Optional comparison on the public pricing page (off by default); only features their module marks as public appear
  there (Design Studio's level and area switches are public)
- Module feature definitions accept a public key (default false)
- The info icon in the Module Features footer shows again

- Module features per plan: modules add their own plan switches (for example the Design Studio level Locked, Brand or
  Full and its areas, with Perfex Design Studio 1.2.1); a matrix on Plans and a section in each plan form; values reach
  workspaces right away; inside a workspace pss_plan_feature() reads them and pss_upgrade_url() links to the portal
- Downgrade grace period: a workspace that moves to a lower plan keeps its previous level for 30 days (setting)
- Design Studio 1.2.0 and later run linked in workspaces; older private copies are swapped on the next upgrade run with
  a backup

1.0.0 — first release
