Fixed

• Item flickering on texture-pack servers — When a server sends a resource pack, Minecraft reloads all textures and re-bakes item models asynchronously. The map item-frame throttle (ItemFrameEntityRendererMixin) kept cancelling updateRenderState calls during this window, leaving frames holding a stale render state that referenced invalidated texture handles — causing visible flickering. A new ResourcePackReloadTracker registers as a Fabric resource reload listener and activates a 60-tick cooldown after every reload; the throttle skips itself while the cooldown is active so render states are always refreshed immediately after a pack change. HUDCache is also reset on reload, so the hotbar dirty-flag system re-evaluates every slot on the first post-reload frame.
• Hotbar cache miss for CustomModelData items — itemStackHash only covered item type, count, damage, and enchantment presence. Texture-pack servers commonly assign the custom_model_data component to items to drive custom model selection; two visually different items sharing the same base data but different CustomModelData values produced identical hashes, causing incorrect "nothing changed" cache hits. The hash now includes CustomModelData.
