## ADDED Requirements

### Requirement: Normalized content items
The system MUST normalize all ingested items (YouTube videos, Instagram posts, podcast episodes) into a single internal schema so the website can render them consistently.

The normalized item MUST include at minimum:
- `id` (stable within its source)
- `source` (`youtube`, `instagram`, or `podcast`)
- `url`
- `title`
- `publishedAt` (ISO-8601)
- `thumbnailUrl` (optional)

#### Scenario: Normalizing a YouTube video
- **WHEN** the system ingests a YouTube video item
- **THEN** it produces a normalized item containing `id`, `source: youtube`, `url`, `title`, and `publishedAt`

#### Scenario: Normalizing a podcast episode
- **WHEN** the system ingests a podcast RSS episode
- **THEN** it produces a normalized item containing `id`, `source: podcast`, `url`, `title`, and `publishedAt`

### Requirement: YouTube ingestion with stats when available
The system MUST support ingesting YouTube videos for channel `youtube.com/santhoshj`.

When a YouTube API key is configured, the system MUST ingest video metadata and MUST ingest view count (and MAY ingest likes/comments if available) so "high-performing" can be computed.

When no YouTube API key is configured, the system MUST still ingest latest videos using a non-authenticated mechanism (for example, channel RSS) but MUST omit performance stats.

#### Scenario: API key configured
- **WHEN** a YouTube API key is configured
- **THEN** the system ingests video metadata and includes `metrics.views` for each ingested video when available from the API

#### Scenario: No API key configured
- **WHEN** no YouTube API key is configured
- **THEN** the system ingests latest videos and does not require `metrics.views` to be present

### Requirement: Podcast RSS ingestion
The system MUST ingest the Irregular Mind podcast RSS feed and produce normalized items representing podcast episodes.

#### Scenario: RSS feed fetch succeeds
- **WHEN** the system fetches the podcast RSS feed successfully
- **THEN** it produces one normalized item per episode with `source: podcast`

### Requirement: Instagram content support via embed-first approach
The system MUST support representing Instagram posts for `@santhoshjanan` in the site content surface.

If API-based ingestion is not configured/available, the system MUST support an embed-first representation where the normalized item contains a `url` to the Instagram post and any additional embed metadata needed by the renderer.

#### Scenario: Embed-first mode
- **WHEN** Instagram API ingestion is not configured
- **THEN** the system provides normalized Instagram items that contain a public post `url` suitable for embedding

### Requirement: Refresh and caching
The system MUST cache the latest successful ingestion output and MUST serve the cached data to the site renderer.

The system MUST support periodic refresh on a schedule (at minimum daily) and MUST support a manual refresh trigger.

On ingestion failure, the system MUST continue serving the most recent cached data.

#### Scenario: Scheduled refresh fails
- **WHEN** a scheduled refresh run fails to fetch one or more sources
- **THEN** the site continues to use the most recent successfully cached dataset

#### Scenario: Manual refresh requested
- **WHEN** a manual refresh is triggered
- **THEN** the system attempts ingestion immediately and updates the cache if ingestion succeeds
