Sopana v1.4.0

Sopāna v1.4.0 — Game-design pass (multiplayer positions, themed 3D characters, richer music)

See where everyone is (multiplayer)

• 3D: each player is now a distinct character standee — the chosen glyph on a player-
  coloured base — standing on their own square; the current player is ringed. No more single
  shared pawn.
• Cinematic: every player appears on the staircase (waiting players dimmed); the active
  player walks and the camera follows them.

Per-theme 3D characters

• The 3D pawn now shows your chosen character (pilgrim, founder, fable animal, hero…), distinct
  per theme and per player.

Richer per-theme music

• Each theme gained a short melodic motif and a win fanfare in its own musical style.

UX / accessibility fixes

• Cinematic controls now wrap on phones so the mute button and turn indicator are always reachable.
• The light Habit Heroes theme no longer washes out the Cinematic or 3D view (dark-clamped
  backdrops); characters stay visible.
• The Cinematic intro now shows each theme's own tagline.
• Lobby is keyboard- and screen-reader-friendly (focus ring + pressed states), and player
  characters default to distinct picks.

Verified on the Android emulator and headless Chromium. 19/19 tests pass.
