- `motion` prop: the Card is the state-domain pilot. Becoming `selected` plays the
preset once via `data-motion-state` (mount-guarded — animates on the transition,
not on mount/deselect). `card-emerge` yields to the motion system when `motion`
is set (otherwise toggling `data-motion-state` re-triggers the mount fade).
- Nested-interactive guard: clicking a control inside an interactive Card (a Footer
button, a link) must not select the Card. `handleActivate`/`handleKeydown` bail
when the event originates from an interactive descendant, and the `:active`
press-scale is suppressed via `:not(:has(button:active, …))` — the press cascade
reaches the ancestor `<button>`, which `stopPropagation` can't touch.
- Demo: `motion` chip control on the live Card.

The shape prop was usable but invisible — add a live `shape` chip control
(rounded/continuous/cut/scoop) to each demo, wired to the live preview + code
snippet, plus a "shape families" patterns row in Badge and a tag-shape control on
TagsInput items. The family system is now discoverable, not just documented.
Verified live (Chrome 146): badge cut -> bevel, button continuous -> squircle,
both flow from the control to the rendered component.

Sprint completo:
- Card (eidos + sema): elevation/intent/interactive, eventos select+activate.
- Avatar: ring, AvatarBadge, AvatarGroup separados; demo Avatar standalone.
- Image: status surface (idle/loading/loaded/error) consumiendo soma ImageProvider.
- SText + STextVirtualList: canvas-text engine portado de morfo-driven-soma como
componentes separados para optimizar bundle (no se importa canvas si no se usa).
- Badge: primitivo eidos puro.
- Trans, FormatNumber, FormatDate, RelativeTime: 4 service components greppables
alrededor de uix.langs y uix.format. Nav group "Utilities".
Bugs fix arts/format/dates (engine-dates.ts):
1. Preset / per-axis conflict: Intl.DateTimeFormat rechaza dateStyle/timeStyle
con cualquier per-axis (weekday/era/year/month/day/dayPeriod/hour/minute/
second/fractionalSecondDigits) o con timeZoneName. Engine drop-ea ambos
presets por defecto cuando detecta conflict (regla estricta — un solo
per-axis hace ilegales los dos presets).
2. Per-call locale override: formatDate/Time/DateTime aceptan tercer arg
locale?: string. No muta engine state. Cache (getCachedDateFormat) keyea
por (locale x options). resolveCallHourCycle: cuando hay locale override
y pref auto, el ciclo horario se resuelve desde el locale OVERRIDE.
3. withHourCycle precedence: caller hourCycle/hour12 ahora gana sobre
preferencia del engine. Antes spread mal ordenado sobrescribia 'h12' del
caller con 'h23' del engine cuando locale resolvia a 24h.
FormatDate component vuelve a rutear siempre por uix.format.dates
(cache + hourCycle + locale reactivo), pasando locale como tercer arg.
Demos service components autonomos del toolbar global: cada uno owns su
demoLocale state con 7 chips (es-ES/en-US/en-GB/de-DE/fr-FR/ja-JP/ar-EG).
FormatDate stage filtra dateStyle/timeStyle por mode + chip hourCycle anadido.
Tests: 14/14 passing en engine-dates.test.ts (+6 nuevos: conflict handling,
locale override, hourCycle precedence).
Docs: arts/format/README.md (handoff 2026-05-25 con las 3 reglas),
README.md por service component, project_service_components_sprint_2026-05-25.md,
feedback_service_demos_own_locale.md (pattern reusable).
