-- A shared passage from the library, sent into a chat.
|
|
--
|
|
-- Modelled as an attachment rather than message text so it can be rendered as
|
|
-- a quote and navigated back to. It reuses the columns the link card already
|
|
-- has, since the shape is the same thing said differently:
|
|
--
|
|
-- url → the ?hl= deep link back to the exact phrase
|
|
-- title → the source reference ("Bhagavad-gītā 2.13")
|
|
-- description → the quoted passage itself
|
|
--
|
|
-- It is a distinct kind rather than a 'link' because it renders as a quote,
|
|
-- not a preview card, and because its URL is always our own — the service
|
|
-- refuses any other origin.
