-- 20260502173044_share_cards_answer_html.sql
--
-- Adds answer_html (nullable text) to public.share_cards so the gallery
-- /said preview can render the same marked.js-produced HTML that the
-- /share/<id> page already renders. Without this, gallery cards
-- HTML-escape the plaintext answer and show literal angle-bracket text
-- where the share page shows formatted lists, bold, code blocks, etc.
--
-- Nullable on purpose: existing rows pre-share-redesign have no rendered
-- HTML captured. The /said handler falls back to escaping the plain
-- answer field for those legacy rows.
--
-- Applied out-of-band via the Supabase Management API
-- (POST /v1/projects/<ref>/database/query). This file lands the change
-- in version control as the canonical record.
