Happy Creeper 1.2.0-beta.1

Third public release and a feature expansion beta build.

Added

• Dedicated companion UI for tamed creepers
• 3D creeper preview in the companion UI
• Helmet and chestplate management directly in the UI
• Fuel slot in the companion UI
• Active status effect icons in the companion UI
• UI title uses the creeper's custom name when named
• Persistent fuel storage on tamed creepers
• Automatic self-healing from stored fuel when below 50% health
• Stored Gunpowder fuel heals 8 HP
• Stored Sweet Gunpowder Biscuit fuel heals 12 HP
• Sweet Gunpowder Biscuits can now be stored as fuel
• Happy Creeper Mask support is now reflected in the main docs and release text

Changed

• Empty-hand right-click now opens the companion UI
• Shift + empty-hand right-click now toggles follow/stay in the world
• Armor management is now centered in the companion UI instead of ad hoc world interactions
• Health display in the UI now uses a heart icon instead of a text label
• Companion UI now reflects the current follow/stay state directly
• Fuel slot layout was moved to the left side of the panel to avoid button overlap

Fixed

• Fuel slot interaction no longer causes the UI health display to fall back to stale 20 HP max health values
• Reusing the same dye on a creeper that already has that color no longer consumes the dye
• Reusing a Rainbow Biscuit on an already-rainbow creeper no longer wastes the item
• Companion UI title now falls back cleanly to Happy Creeper when no custom name exists

Notes

• This is a beta build intended for broader playtesting, not a final release
• Existing 1.21.1 worlds should continue to work
• The companion UI is now the primary place for armor and fuel management
