Semiotic register / 04
Icon system
Thirty-nine equipment signs use one fixed frame and palette. Twenty interface glyphs use one stroke grammar and inherit the surrounding control color.
01 / CONSTRUCTION
A shared 19 × 18 frame
The frame, plate, white separator, coordinate system, and seven sign colors remain identical across every equipment symbol.
The equipment-sign drawings use filled, grid-snapped geometry with consistent optical margins. Micro icons use a 1.5-unit stroke, square structural terminals, and rounded terminals only where direction or motion benefits from them.
Do not recolor sign internals
The fixed palette is part of the equipment-sign grammar. Recolor interface glyphs through color instead.

03 / USE
Reference symbols, preserve semantics
Use role and an accessible label when the icon conveys meaning by itself. Hide decorative icons from assistive technology.

04 / DELIVERY
Use same-document symbols for local Safari previews
Safari may not load an external SVG fragment from a file URL. The System Manual uses Safari-safe direct-file browsing by embedding the generated sprite in every page; HTTP applications may continue using the external sprite.
<!-- External sprite: use when serving the app over HTTP -->
<use href="icons/cargo19-icons.svg#c19-cryogenic"></use>
<!-- Embedded sprite: safe for direct file:// browsing in Safari -->
<!-- Insert cargo19-icons.svg once in the document, then use: -->
<use href="#c19-cryogenic"></use>Manual delivery contract
All 59 symbols are embedded once per generated page. Every live manual icon resolves through a same-document #c19-… reference.
