Three OpenSpec proposals to bring the journal's route/activity detail and feed
closer to best-in-class outdoor apps, in the order we'll implement them:
- activity-sport-type: nullable sport enum on activities (hike/walk/run/
ride/gravel/mtb/ski/other), set on create or normalized on import,
shown as a badge + feed verb, federated as a Note PropertyValue.
- activity-stats: one reusable StatRow + canonical metric set, sport-aware
avg pace/speed, moving-vs-elapsed time. Derive-only, no schema change.
- journal-elevation-profile: elevation profile chart + chart<->map
"active distance" hover/click sync on the read-only detail pages.
All three validate with `openspec validate --strict`. Specs only; no code.
