Development record

When the site build inlines an SVG picture, the alt text the docs page gives it is dropped: the SVG branch of the asset renderer (internal/core/site/assets.go:425-432) returns the drawing wrapped in a span and never uses alt, so the picture's accessible name on the site is whatever the file itself declares (docs/explanation/artefacts.md:13 gives The brief while docs/assets/img/artefact-brief.svg declares brief), and nothing requires an inlined SVG to declare a name at all, so a drawing without one would reach the site unnamed while its page's alt is discarded.
