   Quantum Quill Technologies Ltd — site styles
   Ink & paper minimalism. Signature: the ink line that draws
   itself — a quill's stroke running through the whole site.
   Motion tokens follow the project's animation skill audit:
   strong ease-out entrances, transform/opacity only,
   hover gated to fine pointers, reduced-motion keeps fades.
