No more browser warnings! mkcert creates locally-trusted certs.
Pi Setup:
- Auto-install mkcert during setup
- Generate trusted certs when HTTPS enabled
- Copy CA to /static/ca/rootCA.pem for easy device setup
- New devices can download CA via HTTP and install it
Docker:
- docker-entrypoint.sh checks for mkcert, falls back to openssl
- Shows instructions for CA distribution to other devices
Scripts:
- Added setup-trusted-certs.sh helper for local dev
- Installs mkcert, generates certs, shows device setup instructions
To trust on new devices:
1. Download: http://stegasoo.local/static/ca/rootCA.pem
2. Install as trusted CA in browser/OS

Removed gold outline/stroke from default state - too harsh on
some monitors. Now simple white icons that turn gold on hover
like the header nav, with lift effect and drop shadow.

a "pop" visual cue without glow.
