New

• Delete deck button — a red DELETE button in the deck list, gated on a previewed deck, with a confirm modal.
• Per-ability rows on equipped heroes — each equipped item's ability gets its own clickable row in the ability panel, anchored to the wearing hero.

Improvements

• Deck collection tiles — owned counts now show as filled dots instead of an x3 pill badge.
• Resource panel — numbers and icons bumped up for readability.
• Card tooltip — appears faster (0.25s delay, no fade-in) and now shows equipment gold cost.
• Staging animation — snappier (2.5s → 1.25s).
• Combat direction arrow — hover tooltip with delay and viewport-edge clamping.
• Targeting arrow — strictly reflects valid/invalid, no neutral state.
• AI essence-lane defense — AI now defends essence lanes against match-point loss instead of ignoring them as "healthy".

Fixes

• Hero picker now renders Irina's own art (was showing Spirit of the Spires).
• Howling Vortex now cascades enemies packed against Irina at an edge slot instead of doing nothing.
• Rise Again on a full lane is rejected up-front — no more silently spending 5 mana on nothing.
• Equipment-granted abilities (e.g. Helm of Dominator's Dominate) now show their targeting arrow.
• Board hover glow and active-player avatar outline now clear during shop, hero-deployment, and combat phases.
• Lane slot highlights line up with the correct slot when a lane has sparse valid slots.
• Deploying a hero with no required lane now enables all three lanes as drop targets.
