Erich Blume b0bac91ca9 Fix frontmatter field name for Quartz date display (#158)
## Summary

- Rename `date-modified` -> `modified` in all 80 docs and the `docs-check-frontmatter` task

Quartz's `CreatedModifiedDate` plugin recognizes `modified`, `lastmod`, `updated`, and `last-modified` — but not `date-modified`. The wrong field name caused Quartz to ignore frontmatter dates entirely and fall through to filesystem timestamps (UTC inside Dagger), showing Feb 12 on pages built late on Feb 11 PST.

## Test plan

- [x] `mise run docs-check-frontmatter` passes
- [ ] Kick off docs release after merge — verify rendered dates match frontmatter values

# Loki
Log aggregation system for BlumeOps infrastructure.
## Quick Reference
| Property | Value |
|----------|-------|
| **URL** | https://loki.ops.eblu.me |
| **Tailscale URL** | https://loki.tail8d86e.ts.net |
| **Namespace** | `monitoring` |
| **Image** | `grafana/loki:3.4.2` |
| **Storage** | 50Gi PVC |
| **Retention** | 31 days |
## Architecture
- Single-node deployment with filesystem storage
- TSDB index with 24h period
- Logs collected by [[alloy|Alloy]] and pushed via Loki API
- Queried via [[grafana]]
## Log Sources
**From Indri (via Alloy):**
- forgejo, tailscale (brew services)
- alloy, borgmatic, zot, jellyfin (LaunchAgents)
**From Kubernetes (via Alloy DaemonSet):**
- All pods in all namespaces
**From Fly.io proxy (via embedded Alloy):**
- nginx JSON access logs (`{instance="flyio-proxy", job="flyio-nginx"}`)
## Query Examples (LogQL)
```logql
{service="forgejo"} # All forgejo logs
{service="borgmatic", stream="stderr"} # Borgmatic errors
{host="indri"} |= "error" # All logs containing "error"
{instance="flyio-proxy"} |= "docs.eblu.me" # Fly.io proxy access logs for docs
```
