Cloudflare Custom Hostname a.k.a. Cloudflare for SaaS does not support punycode / emoji domain name
As per title. Is this a bug or expected? Any workaround? Since some of our clients use punycode.

Cloudflare for SaaS
My SaaS, saas.com, allows users to pick a subdomain from a list of predefined domains (a.com, b.com, and dozens more). They can also bring their own domain. In other words: 1. *.saas.com is only used for the SaaS—no UGC (user-generated content)—e.g. the root is for the homepage, while help.saas.com for knowledge base. 2. a.com/b.com redirects to saas.com a.k.a the homepage. Someday they might have their own landing page instead of redirecting. 3. *.a.com and *.b.com are for users. They can pick anything e.g. bla.b.com as long as it's available, not used by other users. 4. They can also bring their own domain, e.g. sub.myco.com. 5. They can also choose nothing. Which means their UCG will be available from the root of a.com/b.com, e.g. a.com/my-ucg. This is the default. Given those requirements, my first question: Where should I enable the "Cloudflare for SaaS" feature? In saas.com? Or in either a.com/b.com? FYI, saas.com, a.com and b.com are all managed in Cloudflare under one account (e.g. [email protected]).

Quick question re: Browser Rendering limit and Queues max_concurrency
I understand that there's a limit of 2 concurrent browsers per account (https://developers.cloudflare.com/browser-rendering/platform/limits/). Since I'm doing rendering inside a Queue, it makes sense that I set its max_concurrency to 2. But looking at the log, all my tasks keep (re)using 1 browser instance. My question: If I set my queue's max_concurrency to >2 (say, 5), what will happen if there's already 2 concurrent browsers running? Will the rest wait, or simply crash?

Upload Cloudflare Image from Workers?
It's not obvious from https://developers.cloudflare.com/images/upload-images/ how to upload images from a Worker. Is it by URL? Considering other services have bindings, I'm thinking there might be something similar for Image.

Validating JWT in Cloudflare Pages (CF's tutorial doesn't work when deployed)
I'm following https://developers.cloudflare.com/cloudflare-one/identity/authorization-cookie/validating-json/ (JavaScript). I understand it's for Express, but I've removed the Express parts and adjusted it for SvelteKit to be deployed in Cloudflare Pages. But when deploying I got this error:

According to https://github.com/cloudflare/workers-sdk/issues/3351 and https://community.cloudflare.com/t/possible-to-set-node-compat-on-pages-functions/448593, they're simply not supported. What should I do?
