Bloom and Serenity UI Wiki & Guide

What Bloom and Serenity UI replaces: every vanilla menu, container screen and HUD icon redrawn as hand-painted artwork, with the world left untouched.
Overview
Bloom and Serenity UI is an interface pack. It does not touch a single block, item or mob - what it replaces is every window the game puts in front of you.
The grey panels become hand-drawn scenes: mossy stone, running water, hanging baskets, flowers. A crafting table looks like a garden workshop, a brewing stand like a cluttered alchemist's bench, a stonecutter like a mason's wall. The HUD is repainted to match, so the hearts, armour, hunger and hotbar belong to the same drawing.
