Without a viewport meta tag, some browsers (notably Firefox with
Fingerprinting Protection active) internally read screen.availWidth /
screen.availHeight to compute the default viewport size, producing the
console warning 'Fingerprinting Protection is altering screen.availWidth
and screen.availHeight'.
Fix:
- Add <meta name="viewport" content="width=device-width, initial-scale=1">
to all five pages that were missing it (dashboard index/flow/logs, agent
index/stats). screen.html already had it.
- Replace window.innerWidth with document.documentElement.clientWidth in
the side-panel drag-resize code in common.js. clientWidth returns the
actual CSS layout viewport width and is not rounded by Firefox's
Fingerprinting Protection, making the drag calculation correct even
with privacy.resistFingerprinting enabled.
