# RULE: a results buffer is a list of things you can RUN, and its traits say
# what a ROW IS. Every list before this one held LOCATIONS — a row with a
# `path:LINE:COL` word inside it — so n/N select that word and Enter Looks it.
# `SPC t t` (ThemeSel) opens the first one whose rows are COMMANDS: `Theme
# <name>`, exactly the line you would type, with no path in it to pick out, so
# n/N select the WHOLE ROW. One motion, two grains, and the same split either
# way — the step only SELECTS, and Tab (Exec, or the middle button, which is
# the same builtin) is what RUNS what it left. Walking the list therefore
# wears nothing as you pass; the theme changes on the Tab, and picking one is
# running it and stopping. There is still no preview state, nothing to confirm
# and nothing to cancel: the row you ran is the theme you have.
#
# Both halves of the ring are in the buffer: the three pardes ships with come
# first (helix, dark, acme), then everything tools/gen_themes.zig exported from
# the vendored helix .toml and zed .json files, sorted. The colors below are
# read with snapstyle, so this proves the generated themes are real data and
# not just names in a list.

# the walk lands IN the pane it steps, so the cursor has been in the list
# since the first n. Body-normal Esc is Last, so it deliberately leaves this
# document-like output buffer open.
# ...and the WHOLE ring is in there, all 228 rows: `ge` to the last line, which
# only reaches `Theme zenburn` if nothing truncated the buffer on the way in. It
# is an ordinary file pane, so it scrolls like one; a motion runs nothing and
# neither does a step, so no theme changes here and the one the last Tab chose
# is still on.
