-- Contact-form messages (issue #80). New table only — nothing to backfill.
-- `author_id` is nullable with ON DELETE SET NULL so a report survives its
-- sender's account deletion (same as ingredients.created_by_id).

-- CreateTable
CREATE TABLE "contact_message" (
    "id" SERIAL NOT NULL,
    "author_id" INTEGER,
    "type" TEXT NOT NULL,
    "message" TEXT NOT NULL,
    "page_url" TEXT,
    "user_agent" TEXT,
    "app_version" TEXT,
    "created_at" TIMESTAMP(3) NOT NULL DEFAULT CURRENT_TIMESTAMP,

    CONSTRAINT "contact_message_pkey" PRIMARY KEY ("id")
);

-- CreateIndex
CREATE INDEX "contact_message_created_at_idx" ON "contact_message"("created_at");

-- AddForeignKey
ALTER TABLE "contact_message" ADD CONSTRAINT "contact_message_author_id_fkey" FOREIGN KEY ("author_id") REFERENCES "user_profiles"("id") ON DELETE SET NULL ON UPDATE CASCADE;
