0.12.3 — warm meeting room

The canvas floor is now a warm wooden meeting room: plank floor, cream walls with terracotta wainscot, whiteboard, wall clock, window with a light shaft, bookshelf / water cooler / plant props, and the team sits around a real wooden table with open laptops when busy.

Bugfix carried from 0.12.2 line: no regressions; all floor interactions verified via automated browser tests (6/6).
