Priority fixes for t-cat.com.tw

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

1. Priority 1 · Accelerate

   HTML compressed

   Observed: The homepage HTML (36 KB) was delivered without gzip, Brotli or zstd compression.

   Why it matters: Compression usually shrinks HTML several times over, so the first bytes of the page arrive sooner on slow connections.

   What to do: Enable Brotli or gzip for text responses (HTML, CSS, JavaScript, JSON, SVG) at the CDN or origin.

   On Cloudflare: Cloudflare compresses eligible responses; check compression rules if HTML arrives uncompressed.

   85% of Postage & Courier Services peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

3. Priority 3 · Harden
