#' Relocate one or more (work)sheets
#'
#' @description
#' Move (work)sheets around within a (spread)Sheet. The outcome is most
#' predictable for these common and simple use cases:
#' * Reorder and move one or more sheets to the front.
#' * Move a single sheet to a specific (but arbitrary) location.
#' * Move multiple sheets to the back with `.after = 100` (`.after` can be
#'   any number greater than or equal to the number of sheets).
#'
#' If your relocation task is more complicated and you are puzzled by the
#' result, break it into a sequence of simpler calls to
#' `sheet_relocate()`.
#'

#' @eval param_sheet(
#'   action = "relocate",
#'   "You can pass a vector to move multiple sheets at once or even a list,",
#'   "if you need to mix names and positions."
#' )
#' @param .before,.after Specification of where to locate the sheets(s)
#'   identified by `sheet`. Exactly one of `.before` and `.after` must be
#'   specified. Refer to an existing sheet by name (via a string) or by position
#'   (via a number).
