+/// The `CarouselModel` helps `ImageCarousel` with some state management logic, keeping track of media sizes, and the ideal display size
+///
+/// This model is necessary because the state management logic required to keep track of media sizes for each one of the carousel items,
+/// and the ideal display size at each moment is not a trivial task.
+///
+/// The rules for the media fill are as follows:
+///  1. The media item should generally have a width that completely fills the width of its parent view
+///  2. The height of the carousel should be adjusted accordingly
+///  3. The only exception to rules 1 and 2 is when the total height would be 20% larger than the height of the device
+///  4. If none of the above can be computed (e.g. due to missing information), default to a reasonable height, where the media item will fit into.
+///
+/// ## Usage notes
+///
+/// The view is has the following state management responsibilities:
+///  1. Watching the size of the images (via the `.observe_image_size` modifier)
+///  2. Notifying this class of geometry reader changes, by setting `geo_size`
+///
+/// ## Implementation notes
+///
+/// This class is organized in a way to reduce stateful behavior and the transiency bugs it can cause.
+///
+/// This is accomplished through the following pattern:
+/// 1. The `current_item_fill` is a published property so that any updates instantly re-render the view
+/// 2. However, `current_item_fill` has a mathematical dependency on other members of this class
+/// 3. Therefore, the members on which the fill property depends on all have `didSet` observers that will cause the `current_item_fill` to be recalculated and published.
+///
+/// This pattern helps ensure that the state is always consistent and that the view is always up-to-date.
+/// 
+/// This class is marked as `@MainActor` since most of its properties are published and should be accessed from the main thread to avoid inconsistent SwiftUI state during renders

+///
+/// The reason is that when using a full screen modifier in those scenarios, the full screen view may abruptly disappear.
+/// One example is when showing videos from the timeline in full screen, where changing the orientation of the device (landscape/portrait)
+/// can cause the source view to be unloaded by the lazy stack, making your full screen overlay to simply disappear, causing a feeling of flakiness to the app
+///
+/// ## Implementation notes
+///
+/// The requests from this function will be received and handled at the top level app view (`ContentView`), which contains a `.damus_full_screen_cover`.
