games: the felt that knows which seat is yours, and the rail you can talk on

Browse Source 
Phase C frontend: the hold'em felt runs on the shared-table runtime.

- holdem.js reads view.your_seat instead of assuming seat zero — every "you"
  test (layout, your cards, the burst on a pot you win, the verdict) is keyed on
  it now, so a joiner at seat 2 sees their own hand at the bottom.
- Leaving is its own endpoint, and a bust closes a solo table; play() animates a
  session-ending hand (the last showdown) before the felt clears.
- A live table: one EventSource per seated player. The server pushes a nudge on
  every table change and a chat line as it is said; a nudge refetches the player's
  own redacted view (a hole card must never ride a frame that fans to the table),
  and a frame that lands mid-animation is held until the script finishes.
- Chat on the felt (a _chat panel, messages only) and a lobby that lists tables
  with a seat going spare. Two-cookie dev rig (reala + bob), with the turn clock
  and reaper live under it.

Browser-confirmed for solo: sit renders your seat and the rail, a hand deals and
conserves to the chip (bought in 100, 100 in front), chat sends. The two-browser
multiplayer pass (join, live sync between windows, shared-table conservation) is
still owed before this deploys.
