demo.picpeak.app sits behind Caddy + Cloudflare; Caddy replaces the
nginx CSP entirely with one that omits 'unsafe-inline' / hash / nonce,
so the #358 inline theme-bootstrap was being blocked there — admin
loaded a black page, the SPA bundle 404'd, link buttons did nothing.
Move the bootstrap to /public/bootstrap.js served as 'self' so the
script runs under every reasonable CSP without further coordination.
Vite copies /public/* to the dist root at build time (same pipeline
as /favicon-32x32.png), and it remains in <head> without defer/async
so it still runs before <body> paints. The OS-preference @media CSS
above still handles the first-frame dark/light baseline.
