| 7 |
* `?desktop_mode_classic=1`). Re-stamps the flag onto every |
| 8 |

| 10 |
* redirects are handled by |
| 11 |
* `openstation_classic_preserve_redirect()` in routing.php. |
| 12 |
* |
| 13 |
* Extracted from `render.php` during the architecture-0.8.1 PHP |
| 14 |
* slicing (phase 6). |

/** |
| 22 |
* Outputs a same-origin admin link/form rewriter for detached ("classic |

* override") tabs. |
| 24 |
* |
| 25 |
* Without this, the first navigation after a detach drops the |
| 26 |
* `desktop_mode_classic=1` flag and the next page falls back to the |
| 27 |
* desktop shell — because the user meta is still `'1'` and the |
| 28 |
* `admin_init` portal redirect kicks in. The JS here re-stamps the flag |
| 29 |
* on every same-origin `/wp-admin/` `<a href>` and `<form action>` so |
| 30 |
* navigations within the tab stay classic, and keeps it in the address |
| 31 |
* bar. Server-side redirects are covered by |
| 32 |
* {@see openstation_classic_preserve_redirect}. |
| 33 |
* |
| 34 |
* Narrowly scoped: only runs when the current request itself carries |
| 35 |
* the classic flag. Skips modifier-clicks (cmd/ctrl/shift/alt), targets |
| 36 |
* other than `_self`, downloads, anchors, and non-http schemes so we |
| 37 |
* don't break "open in new tab" or mailto links. |
