22 changes in this update

Processors tab — the Processor now lives in its own dropdown alongside two new variants.
Chain Processor — takes a feed on BOTH ends, so two belt lines can sell into one square. Unlocks at Rebirth 5 after processing 300 boxes. Max 3.
Golden Tipped Processor — gilded rollers pay x1.5 on every sale, a straight upgrade on the plain Processor. Unlocks at Rebirth 8 after processing 200 Power Cores. Max 3.
Clear Board button — sells every piece on the grid at once, with a confirmation that shows exactly how many pieces go and what you get back.
Drag to erase — hold and drag with the eraser to sell a whole run of belt in one stroke.
Finished buildings now flash green and pop as the engineer steps away.
Demolition takes a piece apart chunk by chunk instead of vanishing it, and pays out with a green $.
The engineer powers up and down with a voice, breathes while it waits, and celebrates a level-up with a ring and a Lv badge.

Rebalanced the tech tree: every percentage upgrade is 10% weaker per level. Because those upgrades multiply together, that works out to roughly a 2.4x cut to late-game income. Tech still resets on rebirth as it always has, and Prestige upgrades are untouched.
The Parts Guide is spread over four pages so nothing is cut off, with proper breathing room between each section heading and its first entry.
Turning the quick bar on or off no longer shifts the whole board sideways.

Unlock popups now cover the whole game — 21 pieces from Rebirth 2 onward used to unlock in complete silence, including every aura tower, the Bridge, Neutronium, Dark Matter, Singularity and all the late-game benches.
Progress bars no longer snap to empty when you buy a process-speed upgrade mid-craft.
Six pieces were missing their colour on the board — Enricher, Gem Cutter, Alloyer, and all three aura towers, which looked identical to each other.
The Bridge was missing its colour stripe in the Conveyors menu.
The hover info card laid its text out sideways instead of stacked.
The Compact button under-reported its own payout by up to 13x. It now shows the Tech Points you will actually bank.
Engineer level-ups were tracked but never shown or heard.

The standalone Processor button — it now lives inside the Processors tab with the two new variants.

After Rebirth 12 the Rebirth button stays locked until the new Titan tech nodes are bought. This is intended, but it currently reads like a bug.
Contract and achievement Tech Point rewards are inflated for Rebirth 12+ players who have maxed their tech.
The board sits slightly left of centre.
