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

Gandi

DNS hosting provider for the eblu.me domain, managed via Pulumi IaC.

Quick Reference

Property	Value
Domain	`eblu.me`
Provider	Gandi LiveDNS
IaC	`pulumi/gandi/`
Stack	`eblu-me`

What It Does

Gandi hosts the DNS records that make *.ops.eblu.me resolve to indri's Tailscale IP (indri.tail8d86e.ts.net). Since Tailscale IPs are not publicly routable, this gives services real DNS names while keeping them private to the tailnet.

The target IP is resolved dynamically from indri.tail8d86e.ts.net at deploy time, so if indri's Tailscale IP changes, re-running the deployment is sufficient.

DNS Records

Private services (Caddy on indri)

Record	Type	Value	TTL
`*.ops.eblu.me`	A	indri's Tailscale IP	300s
`ops.eblu.me`	A	indri's Tailscale IP	300s

Both records point to indri, which runs caddy as the reverse proxy for all private services.

Public services (Fly.io proxy)

Record	Type	Value	TTL
`docs.eblu.me`	CNAME	`blumeops-proxy.fly.dev`	300s

Public CNAMEs point to flyio-proxy on Fly.io. See expose-service-publicly for adding new public services.

See routing for the full service URL map.

Pulumi Configuration

The Pulumi program lives in pulumi/gandi/:

__main__.py - Creates the two A records via pulumiverse_gandi
Pulumi.eblu-me.yaml - Stack config (domain, subdomain)

Stack config values:

Key	Value
`blumeops-dns:domain`	`eblu.me`
`blumeops-dns:subdomain`	`ops`

A break-glass override is available via the BLUMEOPS_REVERSE_PROXY_IP environment variable, which bypasses dynamic IP resolution.

TLS Integration

caddy uses Gandi's API separately (via GANDI_BEARER_TOKEN) for ACME DNS-01 challenges to obtain a wildcard Let's Encrypt certificate for *.ops.eblu.me. This is a different credential from the Pulumi PAT.

Authentication

Gandi requires a Personal Access Token (PAT) for API access. PATs have a maximum lifetime of 90 days (currently set to 30). See gandi-operations for deployment and PAT cycling instructions.
