/**
|
|
* Lightbox — fullscreen image viewer with navigation and EXIF info.
|
|
*
|
|
* Features:
|
|
* - Full-resolution image display
|
|
* - Previous/Next navigation (arrows + swipe)
|
|
* - Close (Esc, click outside, X button)
|
|
* - EXIF metadata panel (fetched on demand)
|
|
* - Keyboard shortcut list (`?` or `h`), deliberately unadvertised
|
|
* - Real fullscreen (`f`), where the browser offers it
|
|
* - Preloads adjacent images
