A compact, finite adaptation of Evolve's primordial evolution loop.

Pinned source commit: 3436358dcd03d9f9e071d51ea071e0a78c0322e4
Upstream authors: Peter Motschmann and Evolve contributors.
Upstream and adapted engine license: Mozilla Public License 2.0 (LICENSE.txt).
The complete preferred source of the adapted engine is engine.js in this bundle.
Original unmodified upstream source is available at the pinned GitHub commit.

Ported mechanics: 2 RNA -> 1 DNA; linear per-count costs for membrane,
organelles, nucleus, eukaryotic cell chambers and mitochondria; capacity
expansions; organelle RNA production; nucleus RNA-consuming DNA production;
150/175/200 DNA evolution milestones. See src/actions.js (actions.evolution,
evolveCosts) and src/main.js (primordial production and capacity calculations).

Changes: original standalone interface and narrative; fourfold production
clock; hold-to-gather; toggleable nuclei; a finite multicellular ending;
three collectible lineages with equal economy; robust local saves; visible-tab
progression; no civilization phase, prestige, network, import/export or account.
This is a fictional incremental game, not a scientific model of evolution.

Visuals: original four-scene atlas generated with the built-in GPT image tool
for this game, optimized locally as life-atlas.webp. Molecular tide, primitive
cell, eukaryotic cell and multicellular colony scenes are integrated into the
live growth stages and ending. No upstream graphic assets are used.
Fonts: device system sans and Georgia; no remote font dependency.
Sound: optional synthesized sine tones; no audio files or network requests.
