/**
|
||
* Branded cold-start splash — a choreographed, premium launch moment.
|
||
*
|
||
* Nostr relays connect over WebSockets that NPool opens lazily; on a fresh load
|
||
* the first content arrives only after the handshakes complete. Rather than show
|
||
* a half-empty map that reads as "is it broken?", we present a short, intentional
|
||
* branded moment while the pre-warmed relays connect and the first spots stream
|
||
* in underneath. It NEVER traps the user:
|
||
*
|
||
* - Determinate progress driven by real milestones (mount → warm → content).
|
||
* - Reveals the instant real content arrives (`skatespots:content-ready`),
|
||
* with a short grace after connection (`skatespots:relays-warm`).
|
||
* - A hard max timeout guarantees dismissal even on a dead/slow network.
|
||
* - A minimum on-screen time prevents a jarring flash on instant loads.
|
||
*
|
||
* Shown once per browser session so in-session navigation never replays it.
|
||
* Fully respects prefers-reduced-motion and safe-area insets; identical on
|
||
* phone and desktop.
