119	* Font Awesome 6, not 5 — and never at the mercy of a shared handle.
120	*
121	* `wordpress-icon-picker` ships a Font Awesome 6 icon list while emitting
122	* FA5-era prefix classes, so a chosen icon is saved as `fas fa-house`. Under
123	* an FA5 stylesheet the `.fas` prefix still resolves and the `<i>` keeps its
124	* box, but `.fa-house:before` is never defined, so `content` stays empty and
125	* the icon renders as blank space in a correctly positioned container. 798 of
126	* the 1873 icons the picker offers are FA6 renames or FA6 additions and fail
127	* exactly this way.
128	*
129	* `fontawesome-frontend-css` is a handle shared with the other Essential
130	* Blocks standalone plugins, and `WP_Dependencies::add()` keeps the first
131	* registration and silently discards the rest. `active_plugins` is sorted, so
132	* `button-group/button-group.php` registers before this file and its Font
133	* Awesome 5.15.2 build takes the handle for the whole site — which is what
134	* emptied this block's icons in both the picker and the saved markup.
135	*
136	* The 6.5.1 registration below is still offered, so a sibling that has no
137	* Font Awesome of its own inherits FA6. But this block no longer depends on
138	* the shared handle: when another plugin already owns it, a private handle is
139	* registered instead, so the FA6 face and the full FA6 glyph set are on the
140	* page no matter who won.

169	* stylesheet order. This layer restates Font Awesome 6 under this block's own

171	* wins on specificity instead, and cannot reach any other plugin's icons.
