Two triggers on one object run in an order Salesforce refuses to promise. The fix is a rule, not a framework.

## The rule

One trigger per object, ever. It contains no logic — it delegates every event to a handler class. Order becomes explicit, bypass becomes possible, tests become sane.

## Enforcing it

A naming convention (AccountTrigger, AccountTriggerHandler) plus a code review checklist is enough. Frameworks help at scale, but the rule is what saves you.

## Practice in your org

- Open your Developer Edition org and follow along step by step
- Change one thing at a time and note what happens
- When something breaks, read the error before searching for it
