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.

* Pre-React theme bootstrap (#358).
|
|
*
|
|
* Loaded as an external script (rather than inline) so a strict CSP
|
|
* with no 'unsafe-inline' / hash / nonce — like the one Caddy puts in
|
|
* front of demo.picpeak.app — does not block it (#564).
|
|
*
|
|
* Reads the per-gallery cached background written by ThemeContext on
|
|
* the previous visit and applies it before React mounts, so revisits
|
|
* land on the right colour from the first frame. The OS-preference
|
|
* default is already handled by the @media CSS in index.html for
|
|
* first-visit / cache-miss callers.
|
|
*
|
|
* Placed in /public so vite copies it to /bootstrap.js at build time
|
|
* (same pipeline as /favicon-32x32.png). Kept in <head> without
|
|
* defer/async so it runs before <body> paints.
