   Tight multi-column masonry grid — each photo keeps its own
   natural crop/aspect ratio and stacks into whichever column is
   shortest, the way a proper architecture-studio portfolio does.
   Narrower columns also mean each photo renders near its native
   resolution instead of being stretched across the full viewport.
   No cards, no shadows, no pop-up. Photos reveal in batches of 6
   as you scroll (see PROJECT PAGE — BATCH REVEAL in main.js).
