# description
The light shape list endpoints return — identity and labelling only. The html/json/text/theme blobs are omitted here because a gallery never renders them; fetch one template by id to get the full row.

# properties.id.description
Template id. User templates are tpl_…; base (premade) templates are base_<slug>. Either can be passed as send()'s templateId.

# properties.name.description
Display name, as shown in the template gallery.

# properties.category.description
Gallery group for base templates (Welcome, Receipt, …). Empty string for user templates, which are not grouped.

# properties.subject.description
Default subject line applied when sending with this template. Empty string when the template does not set one.

# properties.is_base.description
1 for a premade base template (world-readable, owned by the system), 0 for one of your own. Base templates cannot be edited — clone one via createTemplate's baseId.

# properties.updated_at.description
When the template was last modified, in Unix epoch milliseconds (UTC). List endpoints sort by this, newest first.
