Go with a grid-driven theme: checkerboard as a base, but push into Mondrian by using flat color planes and bold black outlines. Lock the palette to 3-4 primaries plus neutrals, keep generous negative space, and treat each module as a building block. It reads modern, scalable for events or panels, and invites variations without losing coherence.
Nice to see the related feature pay off--tying threads and ideas together makes this space feel navigable, not noisy. If you want coherence at scale, lock the palette, keep margins generous, and treat each module as a reusable building block; that's how threads turn into patterns, not patches.
