Machine screens now expose player equipment and optional equipped storage directly, with consistent drawers that remember their state across machines during the current world/server session.

Changes

• Add armor and offhand slots beside player inventory; place color selectors and pause/redstone controls above it and remove the inventory label.
• Add optional Curios equipment/cosmetic slots and a six-column backpack drawer whose tab uses the equipped item's icon.
• Use only generic item-handler insertion/extraction for backpack transfers, including drag distribution, hotbar swaps, and double-click collection. Containers retain their own placement/merging behavior; gestures starting in normal inventory use vanilla handling.
• Share drawer framing and top/bottom insets, allow side configuration to grow into available screen space, and collapse unused settings space.
• Remember drawer choices, backpack page/selection, and automation group across machine screens for the current connection.
• Keep Curios optional and Sophisticated Backpacks/Core as companion development fixtures only. Default manual development clients to 2560 × 1440.

Validation

• check build: 130 JUnit tests, 69 library GameTests, 36 companion GameTests, and release-jar checks passed.
• runCompanionClientSmoke: all five menus, real Curios/backpack interactions, and cross-machine drawer memory passed.
• Added client regressions for normal-inventory left/right drags held across frames, double-click collection with the backpack open, and backpack drags released over player slots.
• runCompanionClientSmoke -PwithoutBackpacks passed with optional mods absent.
• Final build --offline and git diff --check passed.

GUI protocol is now version 6, so clients and servers need matching MMDLib builds. Backpack upgrades/crafting/settings UI is outside this storage integration.

You dodged a lot of bits I was concerned about, so good job!

Must Fix:

1. A dropped drawer request freezes the whole screen for up to 5 seconds, Escrow included
2. Inactive Curios slots accept items -- the code ignores the active flag, so even deactivated slots can be interacted with

Should Fix:

1. The full drawer state is rebuilt every tick even when nothing changed
2. A static field keeps the old world in memory after you disconnect

Cleanups:

1. At least 3 instances of duplicated code spotted
2. You appear to have encoded a size preference -- 2560x1440 -- into the tests. While I have no objection (thats my default monitors fullscreen) and its an offscreen render, its not very nice.
