Priority fixes for lixil.co.jp

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

Priority 1 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.lixil.co.jp.
Why it matters: An enforcing DMARC policy helps receiving mail systems reject email that falsely claims to come from your domain, a common route for phishing your customers.
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.
52% of Smart Home & Lifestyle peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.

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.
51% of Smart Home & Lifestyle peers do this.

Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 76 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
46% of Smart Home & Lifestyle peers do this.

Priority 4 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 76 images and none used loading="lazy".
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
65% of Smart Home & Lifestyle peers do this.
