#!/usr/bin/env python3 """ Measure the sidebar holding many groups, at a phone and a desktop size. Renders the real style.css with the sidebar as `Sidebar()` draws it — twelve groups, the drawer open on the phone — beside a page long enough to scroll, and reports what a person would meet: whether the list scrolls, whether its last group and the legal link can be reached, and whether reaching the end hands the scroll on to the page. What this cannot show is the address bar of a real phone: an iframe has no dynamic toolbar, so `100vh` and `100dvh` measure the same here. sidebar_scroll_probe.py """ import http.server import json import shutil import socketserver import subprocess import sys import tempfile import threading import time from pathlib import Path STATIC = Path(__file__).resolve().parents[2] / "src" / "meshbay_hub" / "static" PORT = 8744 SIZES = [(390, 740), (1280, 800)] GROUPS = "".join( f'' f'' f'A Shared Library Number {i}' f'@owner_account' for i in range(1, 13)) FRAGMENT = f"""
