   edge-density.css — Xeneon Edge fractional-DPR hairline hardening

   DEVICE-ONLY. Gated to the Edge bar: a fractional display scale
   (1.05–1.95 dppx) on a very wide bar (≥ 14:5 aspect). A normal desktop or
   laptop (integer DPR, or a 16:9 / 21:9 window) never matches this query, so
   its appearance is left exactly as designed.

   WHY THIS EXISTS
   The integer-DPR zoom in index.html aligns the PAGE to a whole-pixel grid and
   fixes the gross blur (text is crisp). But measurements on the device show
   iCUE then performs a SECOND, non-uniform resample from its backing surface
   onto the physical 2560×720 panel (~+1% horizontal, ~+3% vertical). That step
   is outside the page's control. A 1px hairline lands between physical pixels
   and breaks up into a dashed / jagged edge — most visible on small CURVED
   borders (the weather pill, the round composer buttons, the topbar buttons).

   THE LEVER (proven the hard way)
   Bumping border OPACITY does NOT help — a 1px line still beats against the
   panel grid. Only THICKNESS does: a solid 1.5px core survives the resample as
   a continuous line. We also tame the soft sun glow, which is the first thing
   to band under a fractional resample. `border-width` is a no-op on elements
   without a border-style, so this never adds a border where there wasn't one.

   This is a PARTIAL improvement: it firms up the few remaining hairlines but
   cannot fully eliminate iCUE's resample (that would require iCUE to render the
   widget at the panel's native resolution, which is its setting, not ours).
