Priority fixes for notepad-plus-plus.org

Ordered by impact and by how common each practice is among peers.

Priority 1 · Enable
robots.txt published
Observed: No robots.txt file was returned at the site root.
Why it matters: robots.txt is where crawlers look first for crawl rules and sitemap locations. Without it, they assume everything is open.
What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.
91% of Programming & Software peers do this. Limit: Only the standard location was requested, once, at the time of the check.

Priority 2 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for no max-age, short of the 30-day benchmark.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
50% of Programming & Software peers do this.
