- Remove backdrop-filter: blur(5px) from .card and .panel — on ARM/Linux
Chromium this is software-rendered, causing severe CPU overhead at 42+
instances. The opaque surface gradient makes blur imperceptible anyway.
- Remove inset vignette box-shadow from .panel added in 51c1014
- Rewrite panel-pulse keyframes to animate opacity only (was box-shadow,
which triggers CPU repaint every frame; opacity is compositor-only)
- Gate body::before and .visuals-container::after scanline pseudo-elements
under [data-animations="off"] — the toggle was blind to both
- Gate panel-indicator pulse under [data-animations="off"] for consistency

ensureModeScript() used document.body.appendChild() to load lazy mode
scripts, but the preload for ?mode= query params runs in <head> before
<body> exists, causing all deep-linked modes to silently fail.
Also fix cross-mode handoffs (BT→BT Locate, WiFi→WiFi Locate,
Spy Stations→Waterfall) that assumed target module was already loaded.

Add theme-aware severity/neon CSS variables and replace hardcoded hex
colors (#fff, #000, #00ff88, #ffcc00, etc.) with var() references
across 26 files so text remains readable in both dark and light themes.
