Why this matters

The production reason.

01
Load charts, editors, maps, and visualizers only on routes that actually need them. This matters because small implementation habits compound across every page, component, and handoff in a production codebase.
02
Use the pattern where the behavior is owned, keep the API small, and make the result easy for another developer to verify later.
03
The goal is not clever code. The goal is predictable code that survives new content, new teammates, and real user traffic.

Platform notes03

How it holds up outside a demo.

FrameworksKeep the pattern close to the route, component, or module that owns the behavior.
CMS or buildersMake the rule reusable so editors do not need to remember implementation details.
ProductionAdd a small check, test, or review note so the pattern does not regress quietly.
