/* ══════════════════════════════════════════════════════════════════════════
   pshell.css — Probily application shell.

   The shell is built on TWO pinned open-source foundations:

     · PatternFly 6.6.0 (MIT, Red Hat) — the visual application-shell
       components: Page, Nav, Menu, MenuToggle, Avatar, Label, Spinner, Alert.
       Consumed as `vendor/patternfly-6.6.0-components.css` plus a subset of
       its design tokens. Every PatternFly class carries the `pf-v6-` prefix,
       which is why it can be dropped into 651 KB of existing unlayered CSS
       without touching a single existing rule — measured: 0 of 381 elements
       moved on the Report page, against 214 for the Bootstrap-derived
       alternative.

     · Unpoly 3.14.3 (MIT) — navigation lifecycle. Its CSS is namespaced to
       `up-*` custom elements and `[up-*]` attributes, so it collides with
       nothing either.

   THIS file is the deliberate mapping from PatternFly's design language to
   Probily's. PatternFly ships as a light-first Red Hat console; Probily is a
   dark amber "Bureau". We do not restyle PatternFly's components rule by rule
   — we re-point the ~40 semantic tokens they are built from at Bureau values,
   which is the supported theming path and survives a PatternFly upgrade.

   Nothing here uses `!important` and nothing here targets a non-`pf-` class
   belonging to another part of the app.
