• A compass and a watch (import … from 'tosijs-3d/dials', not in the barrel: the artwork is 36 KB). Both are drawn by Tonio, and the code only moves their named parts. The compass needle points north as you turn (sceneCompass(b3d) follows the active camera, flat or in a headset; north is +Z). On the watch, a dot on the ring is the time of day (noon at the top, midnight at the bottom) and a dot on the bar is how fast it passes, from still to an hour a second. Drag either: skyWatch(skybox) reads and writes the sky's timeOfDay and realtimeScale. Each goes on the system bar as a <tosi-b3d-panel icon title>. Feather's clock icon is added. bun run dial-art re-embeds the SVGs after they are redrawn.

• A planet and its sphere terrain are one world (#3344). Tonio: "if you pick a point in the middle of what looks like the ocean, coast, mountain range on a planet you end up with corresponding terrain in the sphere terrain and vice versa." Either can be the source, stated by one attribute:

  • <tosi-b3d-terrain planet="#p">: the ground takes its large shape (sea, coasts, mountain ranges) from the planet, scaled to its radius with the sea at 0. Its own detail layer and landforms ride on top, and it rebuilds when the planet changes (planet.shapeKey). Measured at 200 random places: the ground sits within the detail layer of the globe's height (mean 2.5 m, worst 3.9 m with 5 m of detail), and sea or land agrees except at the waterline.
  • <tosi-b3d-planet terrain="#t">: the globe is drawn from the ground's own height function, and again whenever the ground's shape changes. This replaces the hand-written planet.surface = terrain.planetSurface() loop, and the sphere-map demo now uses it.

  Linked, not automatic: a gas giant in a moon's sky, or every body of a star system, must not become the ground you stand on. planet.relativeHeightAt(direction) is the globe's height above its sea as a fraction of its radius. Both attributes are in the schemas.

• Planetary rings catch shadows (#3320). Both are worked out in the shaders for a sphere and a flat ring lit by one star, with no shadow maps. The planet's shadow falls across its rings (the dark wedge behind Saturn): each ring fragment asks whether the ray toward the star passes through the planet, softened slightly at the edge. This applies to any <tosi-b3d-planet> with rings. The rings' shadow bands a gas giant: each fragment finds where the ray toward the star crosses the ring plane and dims by how much ring is there, so the shadow has the ring's own gaps (a lighter stripe where the Cassini gap lets light through). The ring is now one GLSL function (RING_GLSL in gas-giant) that the ring draws itself from and the planet reads, and createGasGiantMaterial takes ring: () => RingShadow | null for a planet built by hand. Not yet: the rings' shadow on a ROCKY planet's surface.
