Priority fixes for starbucks.com.tw

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

Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (58 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 Amazon CloudFront: Enable Compress objects automatically on the cache behaviour.
90% of Food & Grocery Delivery peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

Priority 2 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
87% of Food & Grocery Delivery peers do this.

Priority 3 · 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.
59% of Food & Grocery Delivery peers do this.

Priority 4 · Accelerate
Modern image formats in use
Observed: The homepage had 39 images and none used WebP or AVIF.
