UI5 2.x and Fiori Elements Readiness: UI5 Linter, Deprecated APIs and Regression-Testing Custom Fiori Apps

Prepares custom Fiori and UI5 estates for the legacy-free UI5 SAP has been working toward: what the best practices remove (globals, sync loading, deprecated APIs and libraries) and why, the current status of UI5 2.x (delivery on hold since autumn 2026, cleanup flowing into 1.x), finding problems with the UI5 linter, deciding between remediation and a Fiori elements rebuild with building blocks and the flexible programming model, keeping OPA5 and wdi5 suites green, and a phased plan with regression gates. Built on Contoso Motor Co.'s 38 custom apps.
