Omegle for debate, with a live scoreboard

Build omegle for debate, with a live scoreboard.

Context: Pick a topic, get matched with a stranger who holds the other side, and argue
in real time while a model scores each point as it lands. First to 100 wins.

The scoring is what makes it a game rather than another comment section. Points
for evidence, for actually addressing what the other person said, for
conceding a fair point. Nothing for volume, nothing for insults, nothing for
repeating yourself louder.

Two hard parts, and neither is the matching.

Scoring an argument is a judgement call, and the moment people feel it favours
one side they stop playing. It probably has to show its reasoning for every
point, so a bad call is arguable rather than mysterious.

And a debate site attracts exactly the people you don't want. It needs a
report button, a ban that sticks, and topics that can be switched off — the
first time someone matches into a stranger's abuse, they don't come back.

Worth building the scoring on a fixed topic list before opening it up.

Requirements:
- Ship the smallest version that delivers the core value above, nothing more.
- Pick a stack you can deploy in a day, and state the choice before writing code.
- Handle the empty state, the error state and the offline case explicitly.
- Pricing to build toward: Free to play — it needs volume or nobody gets matched. Money later from ranked
play, tournaments, or schools and debate clubs, where structured practice
against a scored opponent is genuinely worth paying for.

Start by listing the screens, then build them one at a time.
