// that's been bumped for web-grid rendering reasons (the symposion
// timetable snaps to :00/:15/:30/:45 boundaries, so a 9:30 session
// bleeds visually if neighbouring slots anchor :45/:00). The mobile
// app has no grid constraint, so we surface the real attendee-facing
// time. Match by name pattern; offset is in minutes (negative = earlier).
// Underlying startUtc/endUtc are NOT touched so sorting, grouping,
// and add-to-calendar continue to use the canonical timestamps.
