   item-card-v4.css — THE item-card renderer for Nine Lives Network

   Canonical visual for equippable ITEMS (weapons, headwear, outfits,
   shields, familiars) — the sibling of card-v4.css (spell cards).
   Same warm-night palette, same fonts, same rarity language; its own
   `.item-card` / `.ic-*` namespace so the two never collide.

   Link order on a page:
     variables-v2.css  →  components-v2.css  →  item-card-v4.css
   Pair with item-card-v4.js (buildItemCardV4 / initItemCards).

   All design tokens come from variables-v2.css — do NOT redefine them.
