The badge on the homepage and briefing page was static markup, wired
to nothing - flipping a game's status to open in the admin panel had
no effect on it. It's now driven by GameRepository::hasOpenGame() and
only shows while every game is still in development/locked.

Overlay a rotated CSS badge on the homepage hero and briefing page
image instead of baking it into the PNG, so it's easy to remove once
the game ships.
Give the public homepage a themed breach-alert hero and add a /briefing
page with the full mission narrative, both linking into the existing
game dashboard flow.
