+Jinja filter: `inj_features(kind)` filters a list of features to only those
+that actually provide the corresponding snippet template file.
+
+- kind='head' -> roles/sys-srv-web-inj-<feature>/templates/head_sub.j2
+- kind='body' -> roles/sys-srv-web-inj-<feature>/templates/body_sub.j2
+
+If the feature's role directory (roles/sys-srv-web-inj-<feature>) does not
+exist, this filter raises FileNotFoundError.
+
+Usage in a template:
+    {% set head_features = SRV_WEB_INJ_COMP_FEATURES_ALL | inj_features('head') %}
+    {% set body_features = SRV_WEB_INJ_COMP_FEATURES_ALL | inj_features('body') %}
