Replace auto-seed with a browsable template library. Users can
selectively add built-in templates to their collection via a
BookOpen icon or the empty-state prompt. Each library template
tracks its origin via libraryId to prevent duplicates.
- Extract default templates to shared $lib/data/defaultTemplates.ts
- Add GET/POST /api/fitness/templates/library endpoint
- Add library modal with add/added state per template
- Keep seed endpoint as fallback (imports from shared data)
Fat/carb percentages were stored as absolute values that didn't account
for protein g/kg varying with body weight. Now protein calories are
computed first, and remaining calories are split between fat and carbs
by their stored ratio — guaranteeing all macros sum to the calorie goal.
Exercise burned calories also flow into fat/carb targets via a new
effectiveCalorieGoal derived. Goal editor ring preview and labels
updated to show computed actual percentages.
Add protein g/kg (7-day avg using trend weight), calorie balance
(surplus/deficit vs goal), diet adherence (since first tracked day),
and macro split rings with target markers to the stats dashboard.
Clicking "Period Ended" now records yesterday as the end date, since
you only know the period ended the day after. Also added the missing
fertile date range to the ongoing-period status view.
Integrate ExerciseDB v2 data layer (muscleMap.ts, exercisedb.ts) to enrich
the 77 static exercises with detailed muscle targeting, similar exercises,
and expand the catalog to 254 exercises. Add interactive SVG muscle body
diagrams for both the stats page heatmap and exercise list filtering, with
split front/back views flanking the exercise list on desktop. Replace body
part dropdown with unified muscle group multi-select with pill tags.
Full period tracking system for the fitness measure page:
- Period logging with start/end dates, edit/delete support
- EMA-based cycle and period length predictions (α=0.3, 12 future cycles)
- Calendar view with connected range strips, overflow days, today marker
- Fertility window, peak fertility, ovulation, and luteal phase visualization
- Period sharing between users with profile picture avatars
- Cycle/period stats with 95% CI below calendar
- Redesigned profile card as inline header metadata with Venus/Mars icons
- Collapsible weight and period history sections
- Full DE/EN i18n support
Daily food log with calorie and macro tracking against configurable diet
goals (presets: WHO balanced, cut, bulk, keto, etc.). Includes USDA/BLS
food search with portion-based units, favorite ingredients, custom
reusable meals, per-food micronutrient detail pages, and recipe-to-log
integration via AddToFoodLogButton. Extends FitnessGoal with nutrition
targets and adds birth year to user profile for BMR calculation.
Cache fitness page shells and data routes in the service worker so
pages load offline. Queue finished workouts in IndexedDB when the
POST fails and auto-flush them on reconnect. Show an offline banner
on the completion screen so the user knows their workout will sync.
Estimate strength workout energy expenditure using the Lytle et al. multiple
linear regression model. Maps all 77 exercises to 7 studied categories with
confidence levels. Shows kcal on stats page (cumulative), session cards,
workout detail, and workout completion screen. Supports sex/height demographics
via profile section on measure page. Includes info tooltip with DOI reference.
Store a per-user weekly workout target (1-14) in a new FitnessGoal model.
Compute consecutive-week streak from WorkoutSession history via a new
/api/fitness/goal endpoint. Display streak as a 4th lifetime card on the
stats page with an inline goal editor modal.
Use SvelteKit param matchers for bilingual URL routing (e.g. /fitness/stats
and /fitness/statistik). Add centralized i18n module with translation
dictionary, language detection from URL, and path conversion utilities.
Translate all UI text across pages, components, and navigation.
