/* "Paper and ink" look (v41, 2026-11-03). Loaded last, after redesign.css and holo.css.
   Rohesen asked for a site that looks made by a person, not generated: no purple gradient.
   What changed and why:
   - Colours: graphite (night) or stone paper (day), with a teal-to-lime gradient (Rohesen
     picked "Fresh", option B) and teal as the flat accent. No purple.
   - Opaque surfaces instead of frosted glass; the background glow is gone.
   - Headings in Mukta (drawn for Hindi and English by Ek Type, Mumbai).
   - The 3D stays: hero paper stacks, card holograms with their neon glow, and tilt.
   To go back to the old look, remove the human.css <link> from index.html. */
