   INGENIUM CREATUS — Stylesheet  v3
   A studio of Ingenius LLC.

   Brand: Davinci's direction 02, THE MONUMENT — his mark geometry, his type
   (Sora / Manrope / JetBrains Mono) and his layout discipline, carried on
   LEX'S COLOUR TREATMENT at Timn's direction (2026-09-05):
   *"I like the colors both for the webpage and the icon and words that lex
   made, bring that to the new one on top of what Davinci made."*

   So the ground goes back to the cooler #06090C, the accent back to the
   brighter cyan #7FD4E8, and the two-tone treatment returns to both the mark
   and the wordmark.

   DELIBERATE DEPARTURE from Davinci's guardrail: he capped the accent at two
   uses per screen. Timn asked for the two-tone look back, which spends more
   than that. Kept from his rules, because these are objective rather than
   taste: control outlines never use a decorative hairline colour, nothing
   text-bearing drops below 4.5:1, surfaces stay matte, motion stays slow.
   Every value below is MEASURED by the contrast test, not estimated.
