Custom Formatting for Google Templates

I need my existing Google templates to look and feel consistent across the board. The files live in Docs, Sheets, and Slides, and I’m open to improving any or all of them—whichever makes sense once you review the current state. The job is strictly visual: refining typography, colors, spacing, and overall layout so the templates are ready to duplicate and share without further tweaking.

Please take the raw templates I provide, apply a cohesive style that aligns with my brand, and return them to me inside the same Drive folder. Include a quick note on any best-practice settings you use so I can keep the look intact when teammates copy the files. The finished templates should open cleanly, display the updated formatting in every new copy, and require no manual adjustments from my side.
