air_write_attachments(
  base_id,
  table,
  field,
  data,
  parallel = NULL,
  .token = NULL
)

table: Table name or ID.
field: Name of the attachment field.
data: A tibble with airtable_id and file_path columns.
parallel: Logical or NULL. If TRUE, attachment downloads use httr2::req_perform_parallel() (up to 5 concurrent). If NULL, uses option airtable2.parallel or env var AIRTABLE2_PARALLEL (default TRUE).
.token: Personal access token (resolved via air_token() if NULL).

Invisible NULL. Side effect: uploads attachments.
