Constant Summary collapse

BUTTON_TITLE_LENGTH =

WhatsApp button and list row title limits. The choice mapper reads these too, to alias the truncated title it knows this renderer will display for a given choice count.

20
LIST_ROW_TITLE_LENGTH = 
24
MAX_CAPTION_LENGTH =

Meta: "Media asset caption text. Maximum 1024 characters." Documented for image, video, and document messages. Audio and sticker messages' own schemas list only id/link (audio also has voice) - no caption field at all - so they can never carry the numbered body this way, however short it is.

1024
CAPTIONABLE_MEDIA_TYPES = 
[:image, :video, :document].freeze
