Render-blocking Google Fonts and an unused font family

[Harsh-goswami-103]

Problem

src/styles/fonts.css loads fonts via CSS @import (Inter, Plus Jakarta Sans, JetBrains Mono).

• CSS @import is render-blocking and not parallelized.
• No <link rel="preconnect"> to fonts.gstatic.com.
• JetBrains Mono is downloaded but never used anywhere.

Impact

• Slower first paint (blocking font request chained behind CSS).
• Wasted bandwidth fetching unused JetBrains Mono weights.

Acceptance Criteria

• Move font loading to <link> tags in index.html with preconnect, or self-host.
• Drop JetBrains Mono.
• Subset to the weights actually used.

Priority
