 environment: >
 An other-worldly star-forge floating in a deep-space nebula.
 Two shimmering, mirror-image celestial gateways (evoking the Gemini twins)
 arc toward each other, their inner rims alive with spiralling code-runes
 that pulse like liquid starlight. Electric threads of teal and amethyst
 weave between the gates, symbolising continuous integration across worlds.
 focal_elements:
 - A crystalline command-line terminal, semi-transparent, projecting
 holographic constellations of commit hashes and workflow badges.
 - Beneath, a luminous Möbius strip of orbiting GitHub logos forged from
 chrome and nebular plasma, signifying endless automation loops.
 - Distant binary stars casting prismatic lens flares that frame the centre.

 Soft rim-lights outline every structure;
 central volumetric glow accentuates the typography area.
