v2.5.0 "Digital Rain"

Wake up, Neo... the mesh has you.

Three new visualization modes transform the live map into a cyberpunk packet observatory.

🟢 Matrix Mode

Toggle Matrix to shift the entire map into a green phosphor CRT aesthetic:

• Map tiles desaturated and re-tinted green via CSS filter chain
• CRT scanline overlay with subtle flicker
• All node markers dim to dark green
• UI panels, controls, and feed go green-on-black monospace
• Forces dark mode while active; restores your theme on toggle off
• Automatically disables heat map (incompatible combo)

🟢 Matrix Hex Flight

With Matrix enabled, packet animations show actual hex bytes from the raw packet data flowing between nodes:

• Real raw_hex bytes, not generated — what you see is what was on the wire
• White leading byte with triple-layer green neon glow
• Trailing bytes fade from bright to dim, shrinking with distance
• Scrolls through the entire packet payload as it travels each hop
• 60fps via requestAnimationFrame, 1.1s per hop, 300ms fade-out

🟢 Matrix Rain

A separate Rain toggle adds falling hex columns across the screen:

• Each packet spawns a column of its raw hex bytes falling from the top
• Fall distance = hop count — 4+ hops reach the bottom (5 second fall); 1-hop barely drops
• More observations = more rain — each observer spawns its own column, staggered 150ms apart with ±1 hop variation
• All bytes shown — a 40-byte packet displays all 40 bytes trailing behind the leading character
• Canvas-rendered at 60fps — handles hundreds of simultaneous drops with zero DOM overhead
• Works standalone or combined with Matrix mode for the full effect

🐛 Fixes

• Animation null-guard for stale setInterval callbacks after navigation
• WS broadcast null packet on deduplicated observations
• Pause button crash killing WS handler
• Replay button now includes raw hex for rain support
