| 15 | * Save status island plugin implementation. |
| 16 | * |
| 17 | * A dot and a word in the toolbar confirming that the last action reached |
| 18 | * the stored state. Every mutation already persists a revision before the |
| 19 | * response is built, but nothing said so: the undo counter only reports |
| 20 | * how much history exists, and the toast stack is reserved for errors - |
| 21 | * success toasts on every drag would train people to stop reading the |
| 22 | * corner that carries failures. |
| 23 | * |
| 24 | * The label is state, the pulse is event. build() derives the label from |
| 25 | * the instance itself whenever it is called without a status (the initial |
| 26 | * page build, or a plain reload()), so the pip is a standing answer to |
| 27 | * "where does this display stand", not only a flash. An event handler |
| 28 | * passes its own status through $options, which both overrides the label |
| 29 | * for that one render and turns the animation on. |
| 30 | * |
| 31 | * That is why publish, restore and revert are separate statuses rather |
| 32 | * than all folded into "saved": they are the three actions whose outcome |
| 33 | * a user cannot infer from the canvas, and each carries its own color. |
| 34 | * The transient ones (restored, reverted) describe how the display got |
| 35 | * here, so decaying to the plain state label on the next render is |
| 36 | * correct rather than a bug. |
