* applies to `--wp-admin-theme-color` on the parent frame. Themes and |
| 7 |
* plugins can extend or restrict the swatch list via the |
| 8 |
* {@see 'openstation_accent_colors'} filter — e.g. a brand theme that |
| 9 |
* injects its corporate palette, or a compliance plugin that collapses |
| 10 |
* the list to a single approved value. |

* Returns the list of accent-color swatches shown in OS Settings. |
| 19 |
* |
| 20 |
* Each entry is an array shaped `{ id, label, value }`: |
| 21 |
* |
| 22 |
* - `id` is a stable slug (persisted in `localStorage`). |
| 23 |
* - `label` is the human-readable name used in the picker tooltip. |
| 24 |
* - `value` is a hex color applied to `--wp-admin-theme-color`. |
| 25 |
* |
| 26 |
* The defaults ship with six WordPress-adjacent swatches. Consumers |
| 27 |
* mutate the list via the `openstation_accent_colors` filter — entries |
| 28 |
* whose `value` fails `sanitize_hex_color()` are dropped silently so a |
| 29 |
* bad filter return can't inject arbitrary CSS into the shell. |
