## [Unreleased]
### Added
+- `instance.custom_scripts`: operator-injected HTML/JS blocks rendered
+ into every page that extends `base.html`. Each entry takes `name`,
+ `enabled`, `placement` (`head_start` | `head_end` | `body_end`), and
+ `html`. Use for feedback widgets (Marker.io), analytics (GTM,
+ PostHog), error capture (Sentry). Admin-only; rendered with `| safe`
+ — same trust boundary as `instance.logo_svg` / `instance.overview`.
+ Empty default keeps the OSS vendor-neutral. Resolved by
+ `app/instance_config.py::get_custom_scripts()`; surfaced in
+ `/admin/server-config` via `_KNOWN_FIELDS["instance"]`. Example
+ Marker.io block in `config/instance.yaml.example`.

+
+ Reads ``instance.custom_scripts`` from instance.yaml — a list of
+ dicts ``{name, enabled, placement, html}``. Each block lands in one
+ of three template slots:
+
+ - ``head_start`` — first thing in ``
``, before any CSS/JS
+ (rare; GTM dataLayer init).
+ - ``head_end`` — last thing in ```` (default; analytics +
+ feedback widgets like Marker.io, Sentry, Hotjar).
+ - ``body_end`` — just before ```` (vendors that explicitly
+ ask for bottom placement).
+
+ Trust boundary: admin-only. ``instance.yaml`` is written through
+ ``/api/admin/server-config`` (gated by ``require_admin``) and the
+ rendered HTML is interpolated with ``| safe``, exactly mirroring
+ ``instance.logo_svg`` / ``instance.overview``.
+
+ Normalization:
+ - Drop entries with ``enabled=False``.
+ - Drop entries whose ``html`` strips to empty.
+ - Default missing ``name`` to "" and missing ``placement`` to
+ "head_end".
+ - Drop entries whose ``placement`` isn't in the allowlist, with a
+ logged warning naming the offending block — admin sees the
+ mistake instead of the server crashing.
+
+ No env-var override: the structure is a list of objects, which
+ doesn't round-trip cleanly through env vars; deployment-time
+ injection happens by writing the YAML from the deploy script.
+
+ Returns ``[]`` when YAML omits the key — empty by default keeps the
+ OSS vendor-neutral.
