-# Timeline Feature Design
-
-## Objective
-Create a unified timeline view showing Tasks, Meals, Trello Cards, and Google Calendar Events, sorted chronologically.
-
-## Data Sources
-1.  **Tasks (Todoist):** From DB `tasks` table. Filter: `due_date` is not null.
-2.  **Meals (PlanToEat):** From DB `meals` table. Filter: `date` is not null.
-3.  **Cards (Trello):** From DB `cards` table. Filter: `due_date` is not null.
-4.  **Google Calendar Events:** From `GoogleCalendarClient` (Live API).
-
-## Backend Logic
-
-### 1. Data Models (`internal/models/timeline.go`)
-We need a polymorphic structure to hold different item types.
-
-```go
-type TimelineItemType string
-
-const (
-    ItemTypeTask  TimelineItemType = "task"
-    ItemTypeMeal  TimelineItemType = "meal"
-    ItemTypeCard  TimelineItemType = "card"
-    ItemTypeEvent TimelineItemType = "event"
-)
-
-type TimelineItem struct {
-    ID          string           `json:"id"`
-    Type        TimelineItemType `json:"type"`
-    Title       string           `json:"title"`
-    Description string           `json:"description"`
-    Time        time.Time        `json:"time"`
-    AllDay      bool             `json:"all_day"`
-    URL         string           `json:"url"`
-    Meta        map[string]any   `json:"meta"` // Extra data like ProjectName, RecipeURL, etc.
-}
-```
-
-### 2. Store Extensions (`internal/store/`)
-Add methods to fetch items by date range.
-*   `GetTasksByDateRange(start, end time.Time) ([]models.Task, error)`
-*   `GetMealsByDateRange(start, end time.Time) ([]models.Meal, error)`
-*   `GetCardsByDateRange(start, end time.Time) ([]models.Card, error)`
-
-### 3. Logic Layer (`internal/handlers/timeline_logic.go`)
-*   **Function:** `BuildTimeline(store Store, calendarClient *api.GoogleCalendarClient, start, end time.Time) ([]TimelineItem, error)`
-*   **Aggregation:**
-    1.  Fetch from Store (Tasks, Meals, Cards).
-    2.  Fetch from Calendar API.
-    3.  Convert all to `TimelineItem`.
-    4.  **Meal Time Defaults:**
-        *   Breakfast: 08:00
-        *   Lunch: 12:00
-        *   Dinner: 19:00
-        *   Other: 12:00
-    5.  Sort by `Time`.
-
-### 4. HTTP Handler (`internal/handlers/timeline.go`)
-*   **Route:** `GET /timeline`
-*   **Params:** `start` (default: today), `days` (default: 7)
-*   **Response:** Render `timeline-tab.html` partial.
-
-## UI Design (`web/templates/partials/timeline-tab.html`)
-*   **Structure:**
-    *   Container
-    *   Loop through Days
-        *   Date Header (e.g., "Mon, Jan 2")
-        *   List of Items
-            *   Time Column (e.g., "14:00")
-            *   Content Column (Icon + Title + Subtitle)
-*   **Styling:**
-    *   Use existing CSS variables.
-    *   Distinct icons/colors for Tasks vs Meals vs Events.
