Trade path
A dedicated 4B lane, not a recycled quiz page.
Each landing page now uses the same CodeSafe product language: serious, operational, and built around the actual study workflow learners use after they choose a trade.
Safe operating context
Keep safety, plant awareness, and system reasoning visible throughout practice.
Ready for expansion
The page is built like a first-class lane, not a temporary placeholder.
Coverage
Built around the systems learners actually need to master.
The page sets a stronger expectation before signup: clear topics, practical review, and a direct bridge into practice or mock exam flow.
