Stacked on PR B (#22). Merge A → B → C in order.
Step 2 — Audience
- Implement the "Custom Field" audience option (was a stub): field
picker + operator (is / is not / contains) + value input. Estimated
count query joins contact_custom_values with the operator mapped
to eq / neq / ilike. PostgREST ilike handles "contains" case-
insensitively.
- New "Exclude contacts with these tags" section — applies to every
audience type. Estimated count subtracts excluded contacts
client-side against the resolved base set.
- Switching audience type clears stale shape fields (tagIds /
customField / csvContacts) so old selections don't leak across.
Step 3 — Personalize
- Add "Custom Field" mapping option alongside static + contact field.
- Live Preview now pulls the most recent real contact (+ their custom
values) instead of hard-coded sample data. Falls back to sample if
the user has no contacts yet. Rendered in a WhatsApp-style bubble
so the user gets a realistic feel for how the recipient sees it.
Hook — use-broadcast-sending
- AudienceConfig gains customField + excludeTagIds.
- resolveAudience: custom-field branch + exclude-tag subtraction
applied after the base resolution (works for all / tags / custom
field).
- resolveVariables accepts a pre-built (fieldId → value) map per
contact. Before the send loop we bulk-fetch contact_custom_values
for all resolved contacts in one query (paged by 500 for PostgREST
limits) so we never N+1 per recipient.
new/page.tsx — passes customField + excludeTagIds into the hook;
variables state widens to allow type='custom_field'.
