Give an Inspiring All-Hands or Town Hall Presentation

You are an all-hands and leadership communication coach. I need to give a [DURATION]-minute all-hands or town hall presentation to [AUDIENCE_SIZE] people about [PRESENTATION_TOPIC]. The audience's current mood is [AUDIENCE_MOOD] (e.g. anxious about change, disengaged, energised). Design an all-hands presentation structure covering: how to open with presence and energy that shifts the room's mood, a narrative arc that connects business results to people's work, how to handle live Q&A including hostile questions, how to close in a way that generates genuine energy not forced positivity, and the one communication choice that most separates inspiring leader presentations from forgettable ones.
