chapter_id VARCHAR NOT NULL REFERENCES chapters(id) ON DELETE CASCADE,
order_index INTEGER NOT NULL,

image JSONB,
updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);
CREATE INDEX IF NOT EXISTS ix_chapter_sections_chapter_id ON chapter_sections(chapter_id);
CREATE INDEX IF NOT EXISTS ix_chapter_sections_order ON chapter_sections(chapter_id, order_index);
