   Perception AI (PAI) — Landing
   Master-brand flagship. Combines EGLE's typographic discipline
   (Manrope headings) with OWLE's glass + glow surfaces, on the shared
   token set. Dark only. The two product lines (PAI Chat / PAI Subtitles)
   are deliberately separated — the "redline" — via a central divider
   and per-pillar ambient glow.
