The edge-purge integration was reverted in the previous commit; this
finishes the job. Public pages, the feed and /issues.json now say
`public, max-age=300` for browsers and shared caches alike, the code
comments and README explain why the longer s-maxage plus purge design
was dropped, and the rollout runbook loses its purge step, marks the
HTML cache rule optional, and warns to keep the record DNS-only until
the Universal SSL certificate is active.

The README's nginx snippet had drifted from the box: it was missing http2, the
security-headers include, the gzip block, the keepalive bump and the trusted
certificate. Replace it with what actually runs, then add the two CDN changes.
`set_real_ip_from` for Cloudflare's ranges plus `real_ip_header
CF-Connecting-IP` has to come first, or every request looks like it came from
Cloudflare and the login throttle becomes global. Then `X-Forwarded-For` is
*set* from `$remote_addr` rather than appended to: the throttle keys on the
first entry, so a client-supplied header must never survive into the app.
The ranges are listed for reference but the reader is told to regenerate them
from cloudflare.com/ips-v4 and /ips-v6, with a one-liner that does it.
The gzip comment claimed the stylesheet carries 445 KB of base64 fonts; it has
not since the faces moved back out to their own URLs.
The new runbook covers the order that matters: the DNS move (Free plan means a
full nameserver change, so the rest of the zone has to survive it), the zone
settings that are quietly wrong by default — Browser Cache TTL *raises* the
origin's max-age unless set to "Respect Existing Headers", and Rocket Loader and
Email Obfuscation both inject scripts the site's `script-src 'self'` CSP blocks
— the two cache rules, locking the origin to Cloudflare, wiring the purge token,
and the `cf-cache-status` checks that prove each row of the header matrix.
