    // @name Denizen Text Formatting
    // @group Denizen Magic
    // @description
    // Denizen provides a variety of special chat format options like "on_hover" and "on_click".
    // These options exist within Denizen and do not appear in the historical Minecraft legacy chat format that most plugins and systems read.
    // That legacy system has 16 colors (0-9, A-F) and a few toggleable formats (bold, italic, etc). It does not contain anything that needs more than just an on/off.
    //
    // Modern Minecraft, however, supports a JSON based "raw" message format that can do click events, hover events, full RGB colors, etc.
    //
    // Denizen therefore has its own internal system that works like the legacy format system, but also supports the new options normally only available as 'raw JSON'.
    //
    // Because it is entirely processed within Denizen, these options only work within Denizen, when performing actions that support raw JSON input.
    // This magic tool exists to let you write messages without having to write the messy JSON.
    //
    // Be aware that many inputs do not support raw JSON, and as such are limited only the historical Minecraft legacy format.
    // Also be aware that click events, hover events, etc. are exclusively limited to the chat bar and the pages of books, as you cannot mouse over anything else.
    //
    // Also note that RGB colors use a format that Spigot invented, meaning they will work in places that use Spigot's parser OR Denizen's version, but nowhere that uses the vanilla format still.
    //
    // Thanks to Paper's implementation of component APIs where Spigot was too lazy to, Paper servers have advanced text formatting available in more areas.
