+The __fish_scrollback_history_* universal variables are the fish-style source
+of truth — set them via `config-settings` → Paths, or `set -U` directly.
+config.fish exports the SCROLLBACK_HISTORY_* mirrors from them, because the
+POSIX wrapper scripts (paru/yay/tmux/zellij logging and _prune_terminal_logs)
+read the exported names from the environment. When the __fish_ vars are unset,
+the documented defaults are exported. config.fish deliberately does not create
+a global source var, which would shadow the universal and stop live edits from
+taking effect.
 
 Scrollback logs accumulate in SCROLLBACK_HISTORY_DIR as timestamped files.
 When the count exceeds SCROLLBACK_HISTORY_MAX_FILES the oldest are pruned

-    Opens an interactive TUI for managing fish configuration settings. Handles
-    the six opinionated component categories (C1–C6), the master disable

+    Opens an interactive TUI for managing fish configuration settings across
+    four pages, without having to type or remember variable names. Tab cycles
+    forward through the pages; Shift-Tab cycles backward.

+      Session   — the same toggles, current shell only (set -g)
+      Sponge    — sponge history-scrubbing settings: delay, successful exit
+                  codes, purge-only-on-exit, allow-previously-successful, and
+                  extra sensitive variable-name tokens
+      Paths     — scrollback log directory, scrollback max files, and the
+                  user-dots path
 
-    The Dots Path row always operates on the universal scope regardless of the
-    active tab.
+    Toggle rows use ← → (or h/l) along an OFF ← DEFAULT → ON scale; DEFAULT
+    erases the variable so the master switch / built-in default applies. Value
+    rows (the path/int/list settings on the Sponge and Paths pages) use Enter to
+    edit inline; ← / h clears the value back to its default. List rows (e.g.
+    Extra secret, OK codes) accept values separated by commas and/or whitespace
+    — "A, B", "A,B" and "A B" all yield the same two entries. Changes apply
+    immediately. Always available regardless of the __fish_config_opinionated
+    master state.
 
-    Changes to category toggles apply immediately on each keypress. Changes to

+    variables and the exported SCROLLBACK_HISTORY_* mirrors, so the AUR/tmux/
+    zellij log wrappers (which read the exported names) see the change in the
