The seal is built on a hexagonal basalt block (Hauran cut-stone). Three concentric cavea arcs (theatre tiers / civilisational strata) crown a serif B with italic ion subscript. A ledger baseline with four indexed anchors carries a gold pendant diamond — the authorised signature point.
Use the synthesis seal as default. Drop to the compact mark below 32px. Use mono variants for ink/print and single-channel applications. Lockups for headers; monogram for ultra-tight crops.
Every platform crops the profile picture to a circle. These tiles preview that crop. Export at 1080×1080 for crisp display on retina screens. The compact mark and monogram read best at avatar sizes; the synthesis seal works ≥ 400px.
3:1 wide format absorbs platform-specific crops (LinkedIn 4:1, X 3:1, YouTube 16:9-ish). Export at 1500×500 minimum. Logo sits left-of-centre; tagline at the optical baseline.
9:16 vertical for IG / TikTok stories or reel covers. Export at 1080×1920.
