	# --- Build Cycle ---
	# LaTeX requires multiple passes to resolve cross-references and bibliography.

	# 1. First Pass: Compile text, generate .aux files in build dir
	pdflatex -output-directory=$(BUILD_DIR) -interaction=nonstopmode $(TEX_FILE)

	# 2. BibTeX: Process .aux files to generate bibliography (.bbl)
	# ( using || true to allow build to succeed even if no citations exist yet )
	bibtex $(BUILD_DIR)/thesis || true

	# 3. Second Pass: Read .bbl and incorporate bibliography into text
	pdflatex -output-directory=$(BUILD_DIR) -interaction=nonstopmode $(TEX_FILE)

	# 4. Third Pass: Finalize layout and resolve all label/ref links
	pdflatex -output-directory=$(BUILD_DIR) -interaction=nonstopmode $(TEX_FILE)

	# Copy final PDF to output directory
