landformSchemas: the options of volcano, impactCrater, pad, gulley and cover as JSON Schema (asked for by ensemble, tosijs-3d#119, for landform pieces linked to a terrain). x and z carry x-position, so a host can take them from the piece's position. A default worked out from another option (a volcano's craterRadius is radius × 0.22) is marked x-derived: { from, scale } and has no frozen default, so it keeps following its source; landformDerived() works one out. A volcano's activity names its stops (extinct, dormant, semi-active, erupting). The schemas are typed against the options interfaces, and a test checks that spelling out every default draws the same ground as leaving it out.
slider3d({ stops }): named values on a slider's track (tosijs-3d#121): a tick at each, a detent that catches the handle within a few pixels, and the name beside the number while the value is on it. The landing spot for a schema's x-stops.

effectRecipeSchema() says which strings are fetched (tosijs-3d#120): a sound layer's url is format: 'uri-reference', and a particle layer's texture is anyOf a URI (not starting with <) or inline SVG markup (contentMediaType: 'image/svg+xml', x-inline: 'svg'), told apart by the leading < exactly as the player does. Markup is drawn as an image, so nothing it links to is loaded.
