Archive room: mobile shelving for the father and mother archive

Planned (October 2026, user): the archive in the office gets mobile
archive shelving, A-Z Solutions (Vienna) as the reference
(a-z-solutions.eu, checked October 2026: hand wheel or electric drive,
lockable, rails need early floor planning; no published prices).

facility-security.md, new section under Protecting the irreplaceable:
what it holds (fathers and mothers, ~1,200 to 2,400 parts a year; a
reference pressing per title only as a proposal), sizing estimates (about
0.2 kg per part, ~3 mm and ~75 kg per shelf metre; in the Payap office's
~4 x 5.75 m room two fixed runs, four double carriages and one aisle hold
~150 shelf metres, ~50,000 parts, 20+ years), what it asks of the
building (ground slab at full rating, ~11 kN/m2 under the block; rails in
the screed fixed before the floor finish; geared hand wheel; gas,
climate, leak sensor, access control; barcoded box addresses), open
points (quotes from A-Z and a Thai supplier, storage format from the
galvanics vendors, fathers in a second compartment or off site).

Mirrors: site-candidates.md (office ground floor), phase 1 RFQ (archive
keeps the full slab rating if the slab is zoned), digital-factory.md
(archive location as box and shelf position, sets per mother),
equipment-suppliers.md (section 8 entry), total-investment.md added scope
(to quote, not in the sum).
