# Experience First

The product is the experience. Every technical decision either helps or hurts it. When implementation convenience conflicts with user delight, choose delight.

- Say no to 1,000 things (every feature, control, and option must earn its place)
- Ship less, ship better (polished experience with three features beats rough one with ten)
- Prototype before committing (design decisions are cheaper in throwaway HTML than production code)
- Sweat the details (transitions, alignment, spacing, feedback, error states)
- Tighten the core loop (every feature should serve the central workflow or get out of the way)

The user is whoever consumes the work. For a UI that is the end user. For a library or an internal API it is the colleague who imports it. The engineer who maintains the code next is a user too. Weigh their experience the same way, and explain impact from their seat.

Foundations should serve the experience, not the other way around. Foundational thinking governs the *sequence* of work; this principle governs the *target*.
