/* DMACON Technology landing — single-page, mobile-first, dark.
   Palette nods to Workbench 2.x: neutral greys with a single amber
   accent (#FF8800) standing in for a lit DMA-enable bit. Width-capped
   main column so prose stays readable on wide screens without media
   queries. Mono headings + the "$DFF096" eyebrow lean the page toward
   the low-level / retrocomputing register-map feel without going full
   theme-park. */
