Use a true preload for the critical font stylesheet.

rel="stylesheet" with media="print" loads the stylesheet asynchronously, but it does not create a preload. The changed block therefore does not implement the stated preload objective. Use rel="preload" as="style" and switch it to stylesheet in onload, or update the objective and comment to describe asynchronous loading.

In `@layouts/index.html` at line 14, Update the Newsreader font link to use
rel="preload" with as="style", then switch the link to rel="stylesheet" in its
onload handler so it performs a true preload while preserving stylesheet
application.

Load Inter and JetBrains Mono when JavaScript is enabled. The <noscript> fallback is skipped, and the active request loads only Newsreader. The font tokens still require Inter and JetBrains Mono. No other stylesheet loads these families on this path.

In `@layouts/index.html` at line 14, Update the Google Fonts link in the document
head to load Inter and JetBrains Mono alongside Newsreader when JavaScript is
enabled, preserving the existing nonblocking media/onload behavior and ensuring
all required font tokens are available without relying on the noscript fallback.
