+A multiplayer 2D curling game for mobile browser. Any number of clients can join a room, pick Red or Yellow freely, and throw when it is that team's turn (solo pass-and-play or remote opponents).

 ### Controls
 
-- Drag inside the house to place the broom (aim point).
-- Use the team dropdown to choose which team's stone you are throwing.
-- Use the left/right arrow buttons to select curl; the arrow points the direction the stone will curve.
-- Tap **THROW**.
-- The server runs the physics for every stone and streams their paths; the frontend interpolates the animation, so collisions animate smoothly for all stones.
-- Drag anywhere outside the house (or when it's not your turn) to scroll up toward the hog line.
+- When it is your team's turn, drag on the sheet to place the broom (aim point) — aim is not limited to the house.
+- When it is not your turn, drag to pan the ice (default framing shows the house with sidelines; pan up toward the hog line).
+- Use the team dropdown to choose which team's stone you are throwing; switch any time (including mid-end for solo play).
+- Use the left/right curl buttons and the weight/friction controls; friction is a local scalar.
+- Tap **THROW**. Anyone identifying as the turn team may throw.
+- The server runs physics for every stone and streams multi-stone paths; the client animates them on one clock so collisions move together.
