Move the ~130-line $extraJsInline heredoc from admin/system.php into a
static file public/assets/js/system.js, loaded via $extraJs so the
template footer emits a normal <script src=…>.
Replace 4 inline style= attributes with named CSS modifier classes in
system.css:
- style="margin:0;border:none;padding:0" on .srv-section-title
→ .srv-section-title--compact
- style="margin-bottom:.75rem" on sub-heading <h3>
→ .srv-section-title--sub
- style="margin-bottom:0" on .php-grid
→ .php-grid--flush
- style="font-size:.84rem;color:var(--text-secondary)" on <label>
→ .log-toolbar label rule in system.css
The one remaining inline style (--disk-pct / --disk-color CSS custom
properties on .disk-bar) is intentionally kept: it carries PHP runtime
values that cannot be expressed in a static stylesheet.
