Section III · Operating Principles اصول

Restraint is a balance sheet. Four principles guiding the 1969 rebrand of our retail division.

01
Concrete before chrome. Always.
Branch facades are poured in slate-grey concrete with a single steel-blue lintel — never marble veneer, never gilt signage. The building is the logo.
Material standard SC-04 / Slate
02
Two scripts, one grid.
Latin Helvetica and nasta'liq Persian share a baseline of 14mm across every form, plate, and door. The lockup is set once in 1968 and not redrawn.
Spec TS-12.A
03
Indigo is a signature, not a surface.
The deep indigo-purple appears only on the corporate seal, the bond certificate, and the chairman's stationery — under one percent of any printed page.
Coverage cap ≤ 1.0%
04
A document should outlast the desk it sits on.
Forms are typeset in Archivo at 9pt with thin steel-blue rules, archived on cotton stock, and legible after thirty years of fluorescent light.
Archival grade ISO 9706
