Transitions never actually animated: Svelte scopes @keyframes names but does NOT rewrite animation references in inline style attributes, so the inline 'animation: crossfade-in ...' never matched its scoped keyframe — a hard cut, no fade (Ken Burns' zoom was dead too). Move the animation into scoped classes and pass dynamic values via CSS custom properties. - Real two-layer crossfade: hold the outgoing frame opaque beneath the incoming one (which is decode-gated), so there's no black flash and no decode pop. - New slide transitions (from below/left/right) as one reusable component; the previous frame is pushed off the opposite edge in step (a conveyor/push), easeInOutSine 1s. - Fullscreen toggle button (Fullscreen API) + 'f' shortcut; Esc in fullscreen no longer also navigates away. - Controls now reveal on pointer/keyboard activity and fade when idle (cursor hides too) instead of being always visible. - wakelock: null the sentinel on the OS 'release' event so re-acquire-on-visible actually fires (previously the screen could sleep after the tab was first hidden).
