Design a minimalistic logo for 'House Deco' with a focus on the letters ‘HD’ as the centerpiece. The monogram should have very subtle wood grain patterns running through the letters, providing texture without overwhelming the design. Keep the background clean and white for a modern, luxurious feel. The font should be geometric and modern, with smooth lines. Use a natural wood tone, like light ash or deep mahogany, for the monogram to evoke high-end wood craftsmanship, keeping the overall design simple yet elegant.
