generateBrand: resvg loads every system font per render (12s+ on Windows, brand test times out) #120

Bug

generateBrand (packages/ui/src/lib/brand.ts, also run by the brand Vite plugin at every build and dev start) creates one new Resvg(svg, …) per PNG. @resvg/resvg-js loads every system font by default (font.loadSystemFonts: true) on each construction. On Windows that costs ~450 ms per render, so one icon set (6 PNGs) takes ~2.7 s and the unit test that renders three sets takes 12–17 s.

As a result packages/ui/tests/brand.test.ts › generateBrand › writes the hashed icon set; inputs, not pixels, decide the hash times out (5 s) on Windows, so bun run validate and the pre-push gate fail there:

(fail) generateBrand > writes the hashed icon set; inputs, not pixels, decide the hash [13229.13ms]
  ^ this test timed out after 5000ms.

Measured on Windows 11 (Bun 1.4.2), 6 renders of a 512px path-only SVG:

{}                                    2724 ms
{"font":{"loadSystemFonts":false}}      30 ms

Fix

A brand mark is paths. Only load system fonts when the SVG actually has <text>: font: { loadSystemFonts: /<text\b/.test(svg) }. Builds get faster on every OS, and the test passes on Windows.
