Added features (Ore Glow update):

Emissive glow overlays for ore blocks, rendered full-bright regardless of light level using OptiFine's emissive texture system

Covers:

Coal Ore, Iron Ore, Copper Ore, Gold Ore, Redstone Ore, Lapis Ore, Diamond Ore, Emerald Ore — both stone and deepslvariant

Also cover:

Nether Gold Ore, Nether Quartz Ore, and Ancient Debris Each ore has its own colored glow (e.g. cyan for diamond, gold/yellow for gold ore, blue for lapis, red for redstone) to make it easier to spot against plain stone even under fullbright lighting

Original artwork

— standalone _e.png overlay files that sit on top of the vanilla textures, no vanilla assets modified or reproduced

Updated pack.mcmeta

description and README to document the new feature and note that it requires OptiFine (Iris/Sodium needs its own emissive support enabled separately)
