Media & Content `[IMPLEMENTED]`

# Overview

Beyond logos and speaker materials, the platform provides a set of media and content-creation features delivered in Epic 10. These let organizers enrich each event with real photos, teaser imagery, AI-assisted copy, and a live moderator presentation — all from the event detail page.

# Implementation Status

# Event Photos Gallery (Story 10.21)

Organizers upload and manage photos for each event directly from the event detail page’s Photos tab. Uploads use the standard 3-phase presigned-URL flow (request URL → PUT to S3 → confirm), and any photo can be deleted (DB record and S3 object are both removed after a confirmation dialog).

The photos are also surfaced publicly:

• Homepage marquee — the homepage shows real, recent event photos (sampled from the last few events), replacing the previous placeholder testimonials; it falls back to testimonials if too few photos exist.
• Archive pages — each archived event’s detail page shows that event’s own photos in a marquee below the sessions (hidden if the event has no photos).

Public photo listing endpoints (GET /api/v1/events/{eventCode}/photos and GET /api/v1/events/recent-photos) require no authentication.

# Event Teaser Images (Story 10.22)

Organizers upload one or more teaser images for an event from the event settings tab (presigned-URL upload, with a thumbnail gallery and per-image delete; max 10 images per event). On the moderator presentation page, each teaser image renders as its own full-screen slide, inserted in order between the topic-reveal slide and the agenda-preview slide — a visual mood-setter sequence. When an event has no teaser images, the presentation renders exactly as before (no blank slides).

# AI-Assisted Event Content (Story 10.16)

When enabled (gated by the AI_ENABLED feature flag plus a valid OpenAI key), organizers get AI assistance for producing event content in minutes:

• Event description generation — a polished German event description (≈150–200 words) from the topic title.
• Theme image generation — a themed event image generated and uploaded to S3.
• Abstract analysis — scores a speaker’s abstract on two BATbern-specific criteria (absence of product promotion; presence of real-world lessons learned), with feedback and an optional shortened abstract.

When the flag is off (the default), all AI endpoints return 503 and the AI buttons are hidden; if an AI call fails, the UI prompts the organizer to write the content manually. Generation results are cached to avoid duplicate API calls, and each attempt is logged for cost monitoring.

# Moderator Presentation Page (Story 10.8a/b)

A single fullscreen webpage (e.g., /present/BATbern57) that a moderator opens on the projector laptop and drives with a presentation remote — guiding the audience through the evening without ever touching PowerPoint, with content served live from the platform.

• No authentication — loads all event data publicly; navigate with → / ← / PageDown / PageUp / Space; F (or F11) toggles fullscreen.
• Sections — Welcome, About (Verein purpose + partner count), Committee (active organizers), Topic Reveal, teaser-image slides, Agenda Preview, per-speaker sections, Break, Agenda Recap, Upcoming Events, and Apéro. Structural sessions (moderation, networking) are excluded.
• Sidebar — an agenda sidebar appears for the speaker sections and tracks the moderator’s navigation position.
• Animations (Story 10.8b) — a full Framer Motion layer adds the agenda↔sidebar FLIP transition, section slide transitions, a Ken Burns background zoom on the topic image, committee-card stagger, and break/apéro visual effects.
