   `layouts/app.forge.py` wraps every public page's content in a
   `max-w-7xl mx-auto` box — fine for text-heavy sections, but it means a
   naively-styled hero can never actually reach the viewport edges; it's
   boxed inside a box. `.hero-section` breaks out of that ancestor
   constraint with the standard full-bleed trick (`margin-inline: calc(50%
   - 50vw)`) so its background spans the true viewport width, the same way
   a hero on a real marketing site does. `.hero-inner` is the actual content
   grid — single column below 1024px (unchanged mobile behavior), two real
   columns (copy left, code preview right) at 1024px+ — capped at a
   readable max-width and centered, same pattern every other section on
   this page already uses via `.section-container`. */
