{#
_degraded_banner.html — Degraded-State Alert Banner (nav-misc-02)
Renders a role="alert" banner when a page's data read failed, so an outage is
visible to the operator instead of masquerading as a healthy-but-empty page.
See docs/dev/degraded-state-pattern.md.
Template variables (any one truthy triggers the banner):
degraded — bool, preferred flag set by the route on the except path
error — bool, backward-compat flag (some routes use error=True)
Optional:
degraded_detail — short human-readable cause (never rendered raw HTML)
#}
{% if (degraded is defined and degraded) or (error is defined and error) %}
Data temporarily unavailable.
Some content on this page could not be loaded because a backend read failed.
The values shown may be incomplete — this is a system fault, not an
indication that there is no data.
{% if degraded_detail is defined and degraded_detail %}
({{ degraded_detail }})
{% endif %}
