New references/event-portfolio-strategy.md — the strategy layer above roles:
when in-person is necessary (segment fit), the 80/20 of event selection,
size↔ROI inverse (bigger isn't better), the three event types
(owned / trade-show / community) with execution + the community
compound-interest model, and real cost benchmarks. SKILL.md gains a
'Which Events to Invest In (Portfolio First)' section + 2 common
mistakes; new eval (id 7). Distilled from Corey Haines's Founding Marketing.
