Erich Blume ce59e9951b Fix frontmatter field name: date-modified -> modified
Quartz's CreatedModifiedDate plugin recognizes `modified`, `lastmod`,
`updated`, and `last-modified` — but not `date-modified`. The wrong
field name caused Quartz to fall through to filesystem timestamps
(UTC in Dagger), showing incorrect dates on the rendered site.

# Zot
OCI-native container registry providing pull-through cache and private image storage.
## Quick Reference
| Property | Value |
|----------|-------|
| **URL** | https://registry.ops.eblu.me |
| **Local Port** | 5050 |
| **Data** | `~/zot` |
| **Config** | `~/.config/zot/config.json` |
| **LaunchAgent** | mcquack |
## Namespace Convention
| Path | Source |
|------|--------|
| `registry.ops.eblu.me/docker.io/*` | Cached from Docker Hub |
| `registry.ops.eblu.me/ghcr.io/*` | Cached from GHCR |
| `registry.ops.eblu.me/quay.io/*` | Cached from Quay |
| `registry.ops.eblu.me/blumeops/*` | Private images |
## Pull-Through Cache
When [[cluster|minikube]] pulls an image, containerd checks zot first. If cached, returns immediately. If not, zot fetches from upstream, caches it, then returns.
## Security Model
Network access only (no authentication). Defense is the Tailscale ACL boundary.
