PDF-to-LaTeX Template Conversion

I have a finalized document in PDF form that I now need reproduced in clean, well-structured LaTeX. The goal is to mirror the visual appearance of the original file while setting it up in a flexible template so that future edits or content updates are straightforward.

Here is what I’ll provide:
• The source PDF.
• Any original images, graphs, or logo files if they are available separately.

Here is what I need back:
• A complete .tex project (compatible with Overleaf or a local TeX Live setup) that compiles without errors.
• All supporting assets—figures, bibliography file if used, custom class or style files—organised logically.
• A compiled PDF that matches the layout, fonts, spacing and section hierarchy of the original.

Acceptance criteria
1. Running `pdflatex` (or `latexmk`) twice should build the document end-to-end with no warnings that affect output.
2. Visual fidelity: margins, headers/footers, tables, images and equations—where present—line up with the supplied PDF.
3. Code clarity: macros and packages are included only as needed and are commented so I can tweak them later.

If you have experience reconstructing complex layouts—tables, multi-column text, floating figures, mathematical environments—please let me know. A short snippet or example of similar LaTeX work would be a plus.
