## What it is
Idiomorph is a small, dependency-free JavaScript library for morphing one DOM tree into another while preserving element state like focus. It uses id sets to match elements structurally, improving on id-only morphing approaches used by morphdom and nanomorph.

## Use cases
- morph dom trees in place without losing focus or state
- update page content incrementally in a hotwire/turbo app
- preserve dom elements during html swaps in htmx
- diff and patch html fragments client-side
- smooth dom transitions when server renders new html

## When to choose
- you need dom morphing that matches elements based on child structure, not just ids
- you want a tiny, dependency-free library usable via script tag or ESM
- you use Turbo 8 or htmx and want official-grade morphing support

## When to avoid
- you need a full virtual-dom or reactive rendering framework
- your updates are simple full-element replacements where morphing is unnecessary
