Two ways into any Realm, at every depth: click (enamel Panel opens anchored, Enter is the gold-rimmed sky primary) or approach (travel toward it; near the threshold the Realm's gold rim lifts off and pulses as a ring; crossing it changes context). Either way triggers the same entry transition: the medallion swells to fill the view, the ground takes a faint tint of the Realm's hue, and its contents gather in staggered (150ms apart, 900ms settle each). Inside, the eyebrow reads the type + "You're here," the name sits in Goudy, and "← The Field" (or the parent Realm's name) is always the way back. Inside a Realm you work — open Media, build Actors, message Sources, start Actions — and containment recurses like cloisonné cells: an Organization may hold Alliances, Programs, Projects, Relationships, each a smaller Field of its own. Leaving reverses the transition; nothing hard-cuts.
Selected · moon-cream rim OUTSIDE the semantic rim
Threshold · larger low-opacity ring, only near entry
Both · selected while approaching
Recognize (rim, crest, label, nested glints) → Approach (vessel grows; rim starts reading as horizon) → Cross (rim expands beyond viewport; dark core becomes the new ground) → Gather (children settle staggered) → Orient (chrome updates to TYPE · YOU'RE HERE + name + parent path). Click entry 700–1000ms; threshold crossing continuous with travel, final settle 650–900ms; child gather 900ms each at 120–150ms stagger. Never hard-cut, never fade to black, never flood the ground with the Realm hue — faint local tint + reflected rim light only. Click informs before it transports: a click NEVER enters immediately unless the product context established that mode. The threshold is spatial and reversible, not a modal confirmation. Escape reverses the current transient state.
Child type hue stays stable at every depth; parent hue may tint only the parent rim + local reflected light — it never recolors children. The back path names the immediate parent: ← Kinship Duna, never a generic Back; outermost is ← The Field. Inside a Realm, Sources work through Allies: open Media, collaborate with Allies, build Actors, use Resources, initiate Actions — sky blue only on the one consequence-bearing primary in the current view.
