Priority fixes for trmanga.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 1 external script without async or defer.
Why it matters: A plain <script src> in the head stops the browser from showing anything until that file has downloaded and run.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
48% of Literary & Knowledge peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

Priority 2 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for trmanga.com was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
22% of Literary & Knowledge peers do this.
Priority 3 · Enable
Social preview image set
Observed: The homepage had no og:image, so shared links may show without a preview image.
What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.
54% of Literary & Knowledge peers do this.
Priority 4 · Harden
Content Security Policy present
Observed: The homepage response did not include a Content-Security-Policy header.
What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.
18% of Literary & Knowledge peers do this.
