Spindlehearth

Create a digital card for every tool - spindle, spinning wheel, carding paddle, or skein winder - with full provenance and the maker's hallmark. A three-step wizard with a progress bar: first identity (maker's hallmark, craft type, and fiber type), then craftsmanship (orifice and whorl geometry, wood species and joinery, era), and finally provenance (craft tradition region, findspot, where it was calibrated, and mechanical condition). Finished cards come together in a collection with filters by fiber type and show key tags right on the preview. There's a detailed item card with the full specification - from era to the geometry of the parts. A standout feature is the thread field. An interactive visualization of the collection as an orbital network, where each tool is a glowing node on a dark background, connected by threads to the rest. You can tap to spin, drag to rearrange, hold for details, and even "break the thread" with a hard pull. And an archive section with collection analytics: number of hallmarks, era span, percentage of working pieces, a fiber-type breakdown as a ring chart, and classification by craft type.
