/* Halftone screen - the second half of the Old Forge signature (2026-08-08).
   Letterpress IS a dot screen, so this is the printing idiom rather than a
   borrowed one. Deliberately NOT canvas: this page is app.wegweiser.tech for
   anyone not signed in, so it is the one page where a particle system would
   cost us something real.

   Sibling of .lp-grain rather than a layer on it, because .lp-grain carries
   opacity: var(--grain-op) and opacity multiplies down - dots parented there
   could never exceed 5%.

   The mask is what makes it Field B instead of an even screen: dots crowd the
   edges and clear where the words sit. It is fixed, so the vignette tracks the
   viewport as you scroll rather than sliding off. Where mask-image is
   unsupported the dots simply render evenly, which is a poorer version of the
   same idea and not a broken page. */
