Immutable UTF-8 text with canonical language type Str (String is an alias).
Signature
Clones share an Arc allocation. Concatenation creates a new value without implicit conversion. len, indexing, and slices count Unicode scalar values, while allocation limits count UTF-8 bytes. utf8 encodes to Bin and decode validates Bin as UTF-8. Text is the separate visible scene component.

The compatibility spelling resolves to the same immutable text type.
Devices
Use this scene on another device
Show a QR code for your glasses, or send a link to another browser. You can keep working here.
Sharing starts a fresh run of the last compiled code. Your editor draft stays here.
Join a session
Open an invitation link, or paste a link or code from the other device.
Connect your other device
On RayNeo, open Menu → Connect live and scan this code. In another browser, open the invitation link below.
Or enter this code:
Waiting for another device. You can keep working while it connects.
Browsers can edit code; every device can use scene controls. The device that started the session controls playback.
Connection settings
A full invitation link includes its host. With a code alone, both devices need the same live host. Pairing setup
