feat(database): add weapon discovery filters

docs/DESIGN_SYSTEM.md

@@ -1245,6 +1245,13 @@ sets such as Brands and Talents. Always expose selected counts, a single clear
 action, `aria-pressed` state, keyboard focus, and explicit text explaining the
 combination rule. At intermediate width, the bounded facet spans the row above
 two searchable facets; on narrow screens all facet groups stack vertically.
+Weapon discovery applies this pattern to weapon-family icons, damage-type
+icons, and the searchable pool of compatible Talents. Talent facet rows show
+the rendered Tier I description beneath the name. Talent searches match both
+fields case-insensitively so mechanical phrases can discover talents even when
+the talent name is unknown. Brand facets similarly index the names of all
+set-bonus Attributes, allowing players to search by the desired mechanic
+without exposing that metadata as extra visual clutter.
