Avoid surprise image requests, mixed-content failures, and accidental cross-origin leaks when processing fetched markup. `DOMParser` keeps scraped HTML isolated so client-side extraction doesn’t quietly turn into a network and performance problem.

Avoid a post-upgrade boot failure by checking MBR sector alignment and GRUB2’s embedding space before touching apt. The guide flags risky LVM-backed /boot layouts and outlines a recovery path using GPT, a BIOS boot partition, and pvmove.

Keep live camera views current without cache-busting every minute: an iframe-triggered reload lets browsers revalidate the resource, avoid unnecessary transfers, and sidestep the page flicker that makes simple image swaps feel broken.
