Sulfate aerosol injection does not darken the sky. It whitens it — the blue stays, a shade lighter, the sunsets brighten, and a milky aureole opens around the sun. This system takes that pale haze as its ground and builds an assessment document on top of it: injection corridors on plain equirectangular maps, per-region cooling targets, burning-embers risk columns, and the caveat blocks this document type always carries.

Everything is set at UN-grade restraint. Noto for six official languages, Roboto Condensed for dense columns, one blue that is specified rather than chosen, and a risk ramp borrowed intact from the IPCC. No apocalypse, no product hero — the register speaks, and the uncertainty range speaks with it.
