 `symconf` also facilitates dynamically setting system and application "themes," symlinking

+Config files are expected to have names matching the following spec:
+
+<style>-<scheme>.<config_pathname>
+
+- ``config_pathname``: refers to a concrete filename, typically that which is expected by
+  the target app (e.g., ``kitty.conf``). In the context of ``config_map`` in the registry,
+  however, it merely serves as an identifier, as it can be mapped onto any path.
+- ``scheme``: indicates the lightness mode ("light" or "dark")
+- ``style``: general identifier capturing the stylizations applied to the config file.
+  This is typically of the form ``<variant>-<palette>``, i.e., including a reference to a
+  particular color palette. 
+
+For example
+
+```sh
+soft-gruvbox-dark.kitty.conf
+```
+
+gets mapped to 
+
+```sh
+style    -> "soft-gruvbox"
+scheme   -> "dark"

+
+        The prefix order specifies all valid style-scheme combos that can be considered as

+        example, it could be
+
+        ```py
+        [
+            ('none', 'none')
+            ('none', 'dark')

+
+        indicating that either ``none-none.<config>`` or ``none-dark.<config>`` would be
+        considered matching pathnames, with the latter being preferred.
+
+        This method exists because we need a way to allow any of the combos in the prefix
+        order to match the candidate files. We don't know a priori how good of a match
+        will be available, so we consider each file for each of the prefixes, and take the
+        latest/best match for each unique config pathname (allowing for a "soft" match).
+        
+        .. admonition: Checking for matches
+
+            When thinking about how best to structure this method, it initially felt like
+            indexing factors of the FileParts would make the most sense, preventing the
+            inner loop that needs to inspect each FilePart for each element of the prefix
+            order. But indexing the file parts and checking against prefixes isn't so
+            straightforward, as we'd still need to check matches by factor. For instance,
+            if we index by style-scheme, either are allowed to be "any," so we'd need to
+            check for the 4 valid combos and join the matching lists. If we index by both
+            factors individually, we may have several files associated with a given key,
+            and then need to coordinate the checks across both to ensure they belong to
+            the same file.
+
+            In any case, you should be able to do this in a way that's a bit more
+            efficient, but the loop and the simple conditionals is just much simpler to
+            follow. We're also talking about at most 10s of files, so it really doesn't
+            matter.

+        Isolate the best match in a match list and find its relaxed variants.
+
+        This method allows us to use the ``match_paths()`` method for matching templates
+        rather than direct user config files. In the latter case, we want to symlink the
+        single best config file match for each stem, across all stems with matching
+        prefixes (e.g., ``none-dark.config.a`` and ``solarized-dark.config.b`` have two
+        separate stems with prefixes that could match ``scheme=dark, style=any`` query).
+        We can find these files by just indexing the ``match_path`` outputs (i.e., all
+        matches) by config pathname and taking the one that appears latest (under the
+        prefix order) for each unique value.
+
+        In the template matching case, we want only a single best file match, period
+        (there's really no notion of "config stems," it's just the prefixes). Once that
+        match has been found, we can then "relax" either the scheme or style (or both) to
+        ``none``, and if the corresponding files exist, we use those as parts of the
+        template keys. For example, if we match ``solarized-dark.toml``, we would also
+        consider the values in ``none-dark.toml`` if available. The TOML values that are
+        defined in the most specific (i.e., better under the prefix order) match are
+        loaded "on top of" those less specific matches, overwriting keys when there's a
+        conflict. ``none-dark.toml``, for instance, might define a general dark scheme
+        background color, but a more specific definition in ``solarized-dark.toml`` would
+        take precedent. These TOML files would be stacked before using the resulting

+    _not_ when affected groups overlap.
+
+    For example, if an outer call is setting the foreground color (e.g., ``Fore.GREEN``),
+    nested calls on the text being passed into the function can modify and reset the
+    background or style with affecting the foreground. The primary use case here is
+    styling a group of text a single color, but applying ``BRIGHT`` or ``DIM`` styles only
+    to some text elements within. If we didn't reset by group, the outer coloration
+    request will be "canceled out" as soon as the first inner call is made (since the
+    unconditional behavior just employs ``Style.RESET_ALL``).
