Score webinar leads for sales follow-up

Using my Livestorm data, sort everyone who registered for the most recent session of [WEBINAR NAME] that already took place into follow-up tiers. Count participants only, not team members. Use these tiers, in this order: [TIER RULES]. Base them on what the data shows: whether they attended, their time present, questions asked, chat messages, poll votes, and whether no-shows watched the replay. If the per-person chat counts are all zero, count each person's messages from the session's chat instead, matching each message to its author. Give me the number of people per tier, a table per tier with name, email, company if my form asks for it and the signals that put them there, and a suggested next step for each tier. Finish with the whole list as a CSV I can import into my CRM.
