## Overview
Sunday.fitness is a social fitness platform where athletes track workouts,
follow AI-personalised training plans, join groups and challenges, and compete
on segment and route leaderboards. The app works on iOS, Android and the web,
and is bundled in the Hakonava / Sunday codebase.

Key surfaces (each deep-linkable by integer id):
- Workouts — completed activities recorded by athletes
- Activity schedules / training plans — upcoming or planned activities
- Segments (routes) — climbable, leaderboard timing targets
- Recurring routes (myroutes) — an athlete's own repeated favourites
- Groups — crews that train together
- Challenges and goals — publicly shared objectives
- Athletes — public profile pages

## Entity deep links
These resolve to server-rendered Open Graph + JSON-LD pages (one per id), so an
