 # Platform design contract
 
-Applies to this independent Next.js application, the zone served at `/org`, and to `design-system/`. `embedded/` is not part of that application; it has [its own section](#embedded-in-the-organization-surface). In this tree “EMCN” means the Sim Platform design system in `design-system/`. The existing app and `packages/emcn` remain isolated. For new work or design drift, run the repository's `$implement-platform` skill. Its Paper companion is `$sim-paper-design`. Never import the legacy app, styles, chrome, business logic or providers across this boundary. Real data crosses only through the [data seam](#phase-3-data-seam).

 Interface strokes have one non-scaling optical weight in CSS pixels. Size glyphs relative to the control’s type, capped at the shared icon size. Paint interface strokes with opaque semantic ink so overlapping segments do not darken; branded artwork and chart marks retain their own geometry. Neutral quiet controls gain the hover surface without changing ink. Destructive and primary confirmations change perceived lightness by the same amount within each theme; check rendered colors, not blend percentages. Destructive menu commands turn red on hover or keyboard highlight. A compact × dismisses a tab, recent, draft attachment or recipient with the ordinary quiet IconButton. Callers choose intent, never paint. A selectable menu row gains the same surface and promotes its glyph from secondary to primary ink on hover or active keyboard navigation. Selection, disabled and inverse controls have distinct semantics. Never change stroke thickness, spacing or radius on hover. Render interface glyphs through `Icon`. A unique data graphic may own accessible, labeled SVG and paint its own marks. Pointer focus alone adds no paint.
 
-Use [the shared Platform time formatters](lib/time.ts) for displayed ages, clocks, calendar ranges and chart dates. Keep raw instants or ISO calendar days in data. Relative ages use a single reference instant for the surface: now below one minute, whole minutes below an hour, hours below 24 hours, then `1d ago` until 48 hours. After that show an ordinal date, including the year when it differs. Preserve calendar days across time zones. Pass the viewer’s zone for a locally composed message. Fixture time is server-gated and fixed for reproducible rendering. A Home activity chart keeps one visibility setting and one period across modes: Build shows Tasks run and Search shows Searches. Both draw real dated daily counts; the axis, tooltip and Customize Home label must agree with the selected metric.
