# Echo's verb methods are SHOUTING-CASE: `e.GET("/x", h)`, `e.POST(...)`,
# etc. Common router variable names: e (engine), router, g (group), api,
# server. Group prefixing — `g := e.Group("/api"); g.GET("/users", ...)`
# — is intentionally NOT concatenated: the inventory records the literal
# path argument and leaves prefix synthesis to the future synthesizer.
