Most decks fall apart the moment someone other than the designer touches them. A layout that only works in the original presenter's hands isn't a template - it's a liability. I build presentation systems from narrative structure outward: what's the argument, what's the hierarchy, where does the audience need to breathe.

Then I design the visual framework around that so anyone on the team can update a slide, swap a chart, or restructure a section without the whole thing collapsing. Clean master slides, locked type systems, logical naming. The kind of backstage discipline that means the person presenting can focus on the room instead of fighting the file.
