+//! Seoul256 (233): Seoul256, as close to the original as pardes can draw it.
+//! Every value is the original's own, cited on its line (path:line key); the
+//! chrome pardes needs and the original lacks is derived from its palette.
+//! Sources:
+//!   repo; url https://github.com/junegunn/seoul256.vim; genizah ~/05-genizah/seoul256.vim; commit 0357ff3e44faab66c98bc98dfc89c834e37012da
+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag text #dfdebd -> #12120f: 3.02:1 on #9a7372, tag text needs 4.5:1
+//!   - focused grip #007173 -> #006a6c: 1.40:1 on the focused tag #9a7372
+//!   - rules between panes #000000 -> #3d3d3d: 1.17:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)
+//! Upstream notes: g:seoul256_background = 233 (dark). Resolved exactly as
+//! ~/05-genizah/seoul256.vim/colors/seoul256.vim:145-177: dark_bg=233,
+//! light_bg=253, dark_bg_2=16 (line 175: dark_bg>233 ? dark_bg-2 : 16),
+//! light_bg_1=254, light_bg_2=255 (lines 176-177, min(..,256)); s:hi uses the
+//! first (dark) list element (s:style_idx, line 165) and maps any index >255 to
+//! 231 (lines 184-185). GUI hex from the file's default s:rgb_map
+//! (~/05-genizah/seoul256.vim/colors/seoul256.vim:120-135, iTerm2-measured
+//! values; NOT the xterm table, which is only used when g:seoul256_srgb=1,
+//! lines 37-118). The background knob is a fixed integer set: dark 233..239
+//! (default 237), light 252..256 (default 253) (lines 147-150, 169/173;
+//! README.md:52-60); any other value is discarded (line 152) and the style
+//! falls back to &background/colors_name; non-integers are not meaningful
+//! because the offsets index a Dict by integer. StatusLine/StatusLineNC are
+//! gui=bold,reverse so status roles are the rendered (swapped) colours. No
+//! Diagnostic* groups (error/warning from ALE signs, info/hint null). ansi: the
+//! colorscheme sets no g:terminal_ansi_colors/terminal_color_*; ansi is the
+//! repo's own urxvt port, which exists for one background only (237) and is
+//! reused unchanged for every level. Index gaps: for this level the roles
+//! tabline_fg land on an xterm index missing from the default s:rgb_map, so Vim
+//! emits gui*=NONE and they inherit Normal (given as such).

+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag text #dfdebd -> #12120f: 3.02:1 on #9a7372, tag text needs 4.5:1

+//!   - rules between panes #060606 -> #4a4a4a: 1.32:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)

+//! README.md:52-60); any other value is discarded (line 152) and the style
+//! falls back to &background/colors_name; non-integers are not meaningful
+//! because the offsets index a Dict by integer. StatusLine/StatusLineNC are
+//! gui=bold,reverse so status roles are the rendered (swapped) colours. No
+//! Diagnostic* groups (error/warning from ALE signs, info/hint null). ansi: the
+//! colorscheme sets no g:terminal_ansi_colors/terminal_color_*; ansi is the
+//! repo's own urxvt port, which exists for one background only (237) and is
+//! reused unchanged for every level. Index gaps: for this level the roles
+//! tabline_fg land on an xterm index missing from the default s:rgb_map, so Vim
+//! emits gui*=NONE and they inherit Normal (given as such).

+//! Seoul256 (236): Seoul256, as close to the original as pardes can draw it.
+//! Every value is the original's own, cited on its line (path:line key); the
+//! chrome pardes needs and the original lacks is derived from its palette.
+//! Sources:
+//!   repo; url https://github.com/junegunn/seoul256.vim; genizah ~/05-genizah/seoul256.vim; commit 0357ff3e44faab66c98bc98dfc89c834e37012da
+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag text #dfdebd -> #12120f: 3.02:1 on #9a7372, tag text needs 4.5:1
+//!   - focused grip #007173 -> #006a6c: 1.40:1 on the focused tag #9a7372
+//!   - rules between panes #252525 -> #5f5f5f: 1.46:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)
+//! Upstream notes: g:seoul256_background = 236 (dark). Resolved exactly as
+//! ~/05-genizah/seoul256.vim/colors/seoul256.vim:145-177: dark_bg=236,
+//! light_bg=253, dark_bg_2=234 (line 175: dark_bg>233 ? dark_bg-2 : 16),
+//! light_bg_1=254, light_bg_2=255 (lines 176-177, min(..,256)); s:hi uses the
+//! first (dark) list element (s:style_idx, line 165) and maps any index >255 to
+//! 231 (lines 184-185). GUI hex from the file's default s:rgb_map
+//! (~/05-genizah/seoul256.vim/colors/seoul256.vim:120-135, iTerm2-measured
+//! values; NOT the xterm table, which is only used when g:seoul256_srgb=1,
+//! lines 37-118). The background knob is a fixed integer set: dark 233..239
+//! (default 237), light 252..256 (default 253) (lines 147-150, 169/173;
+//! README.md:52-60); any other value is discarded (line 152) and the style
+//! falls back to &background/colors_name; non-integers are not meaningful
+//! because the offsets index a Dict by integer. StatusLine/StatusLineNC are
+//! gui=bold,reverse so status roles are the rendered (swapped) colours. No

+//! Seoul256 (237): Seoul256, as close to the original as pardes can draw it.
+//! Every value is the original's own, cited on its line (path:line key); the
+//! chrome pardes needs and the original lacks is derived from its palette.
+//! Sources:
+//!   repo; url https://github.com/junegunn/seoul256.vim; genizah ~/05-genizah/seoul256.vim; commit 0357ff3e44faab66c98bc98dfc89c834e37012da
+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag ground #9a7372 -> #9d7473: 1.50:1 off the unfocused #616161, pardes needs 1.5:1 on a dark page
+//!   - focused tag text #dfdebd -> #12120f: 2.96:1 on #9d7473, tag text needs 4.5:1
+//!   - focused grip #007173 -> #006c6e: 1.43:1 on the focused tag #9d7473
+//!   - rules between panes #333233 -> #6b6b6b: 1.46:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)
+//! Upstream notes: g:seoul256_background = 237 (dark). Resolved exactly as
+//! ~/05-genizah/seoul256.vim/colors/seoul256.vim:145-177: dark_bg=237,
+//! light_bg=253, dark_bg_2=235 (line 175: dark_bg>233 ? dark_bg-2 : 16),
+//! light_bg_1=254, light_bg_2=255 (lines 176-177, min(..,256)); s:hi uses the
+//! first (dark) list element (s:style_idx, line 165) and maps any index >255 to
+//! 231 (lines 184-185). GUI hex from the file's default s:rgb_map
+//! (~/05-genizah/seoul256.vim/colors/seoul256.vim:120-135, iTerm2-measured
+//! values; NOT the xterm table, which is only used when g:seoul256_srgb=1,
+//! lines 37-118). The background knob is a fixed integer set: dark 233..239
+//! (default 237), light 252..256 (default 253) (lines 147-150, 169/173;
+//! README.md:52-60); any other value is discarded (line 152) and the style
+//! falls back to &background/colors_name; non-integers are not meaningful
+//! because the offsets index a Dict by integer. StatusLine/StatusLineNC are
+//! gui=bold,reverse so status roles are the rendered (swapped) colours. No
+//! Diagnostic* groups (error/warning from ALE signs, info/hint null). ansi: the
+//! colorscheme sets no g:terminal_ansi_colors/terminal_color_*; ansi is the
+//! repo's own urxvt port, which exists for one background only (237) and is
+//! reused unchanged for every level.

+//! Seoul256 (238): Seoul256, as close to the original as pardes can draw it.

+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag ground #9a7372 -> #b97877: 1.29:1 off the unfocused #6b6b6b, pardes needs 1.5:1 on a dark page
+//!   - unfocused tag text #dfdebd -> #eeeddb: 3.89:1 on #6b6b6b, tag text needs 4.5:1 to be read and run
+//!   - focused tag text #dfdebd -> #1f1f1a: 2.55:1 on #b97877, tag text needs 4.5:1
+//!   - rules between panes #3f3f3f -> #767676: 1.43:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)

+//! Seoul256 Light (252): Seoul256, as close to the original as pardes can draw it.
+//! Every value is the original's own, cited on its line (path:line key); the
+//! chrome pardes needs and the original lacks is derived from its palette.
+//! Sources:
+//!   repo; url https://github.com/junegunn/seoul256.vim; genizah ~/05-genizah/seoul256.vim; commit 0357ff3e44faab66c98bc98dfc89c834e37012da
+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - unfocused tag text #565656 -> #545454: 4.39:1 on #c8c8c8, tag text needs 4.5:1 to be read and run
+//!   - focused tag text #dfdebd -> #12120f: 3.02:1 on #9a7372, tag text needs 4.5:1
+//!   - focused grip #719899 -> #4b6465: 1.31:1 on the focused tag #9a7372
+//!   - rules between panes #bfbfbf -> #acacac: 1.30:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)
+//! Upstream notes: g:seoul256_background = 252 (light). Resolved exactly as
+//! ~/05-genizah/seoul256.vim/colors/seoul256.vim:145-177: dark_bg=237,
+//! light_bg=252, dark_bg_2=235 (line 175: dark_bg>233 ? dark_bg-2 : 16),
+//! light_bg_1=253, light_bg_2=254 (lines 176-177, min(..,256)); s:hi uses the
+//! second (light) list element (s:style_idx, line 165) and maps any index >255
+//! to 231 (lines 184-185). GUI hex from the file's default s:rgb_map
+//! (~/05-genizah/seoul256.vim/colors/seoul256.vim:120-135, iTerm2-measured
+//! values; NOT the xterm table, which is only used when g:seoul256_srgb=1,
+//! lines 37-118). The background knob is a fixed integer set: dark 233..239
+//! (default 237), light 252..256 (default 253) (lines 147-150, 169/173;
+//! README.md:52-60); any other value is discarded (line 152) and the style
+//! falls back to &background/colors_name; non-integers are not meaningful
+//! because the offsets index a Dict by integer. StatusLine/StatusLineNC are
+//! gui=bold,reverse so status roles are the rendered (swapped) colours. No
+//! Diagnostic* groups (error/warning from ALE signs, info/hint null). ansi: the
+//! colorscheme sets no g:terminal_ansi_colors/terminal_color_*; ansi is the
+//! repo's own urxvt port, which exists for one background only (253) and is
+//! reused unchanged for every level. Index gaps: for this level the roles
+//! tabline_bg land on an xterm index missing from the default s:rgb_map, so Vim
+//! emits gui*=NONE and they inherit Normal (given as such).

+//! Seoul256 Light (253): Seoul256, as close to the original as pardes can draw it.
+//! Every value is the original's own, cited on its line (path:line key); the
+//! chrome pardes needs and the original lacks is derived from its palette.
+//! Sources:
+//!   repo; url https://github.com/junegunn/seoul256.vim; genizah ~/05-genizah/seoul256.vim; commit 0357ff3e44faab66c98bc98dfc89c834e37012da
+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag text #dfdebd -> #12120f: 3.02:1 on #9a7372, tag text needs 4.5:1
+//!   - focused grip #719899 -> #4b6465: 1.31:1 on the focused tag #9a7372
+//!   - rules between panes #c8c8c8 -> #b3b3b3: 1.28:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)
+//! Upstream notes: g:seoul256_background = 253 (light). Resolved exactly as

+//! light_bg_1=254, light_bg_2=255 (lines 176-177, min(..,256)); s:hi uses the

+//! (~/05-genizah/seoul256.vim/colors/seoul256.vim:120-135, iTerm2-measured
+//! values; NOT the xterm table, which is only used when g:seoul256_srgb=1,
+//! lines 37-118). The background knob is a fixed integer set: dark 233..239
+//! (default 237), light 252..256 (default 253) (lines 147-150, 169/173;
+//! README.md:52-60); any other value is discarded (line 152) and the style
+//! falls back to &background/colors_name; non-integers are not meaningful
+//! because the offsets index a Dict by integer. StatusLine/StatusLineNC are
+//! gui=bold,reverse so status roles are the rendered (swapped) colours. No
+//! Diagnostic* groups (error/warning from ALE signs, info/hint null). ansi: the
+//! colorscheme sets no g:terminal_ansi_colors/terminal_color_*; ansi is the
+//! repo's own urxvt port, which exists for one background only (253) and is
+//! reused unchanged for every level.

+//! Seoul256 Light (255): Seoul256, as close to the original as pardes can draw it.
+//! Every value is the original's own, cited on its line (path:line key); the
+//! chrome pardes needs and the original lacks is derived from its palette.
+//! Sources:
+//!   repo; url https://github.com/junegunn/seoul256.vim; genizah ~/05-genizah/seoul256.vim; commit 0357ff3e44faab66c98bc98dfc89c834e37012da
+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag text #dfdebd -> #12120f: 3.02:1 on #9a7372, tag text needs 4.5:1
+//!   - focused grip #719899 -> #4b6465: 1.31:1 on the focused tag #9a7372
+//!   - rules between panes #d9d9d9 -> #bfbfbf: 1.25:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)
+//! Upstream notes: g:seoul256_background = 255 (light). Resolved exactly as
+//! ~/05-genizah/seoul256.vim/colors/seoul256.vim:145-177: dark_bg=237,

+//! Seoul256 Light (256): Seoul256, as close to the original as pardes can draw it.
+//! Every value is the original's own, cited on its line (path:line key); the
+//! chrome pardes needs and the original lacks is derived from its palette.
+//! Sources:
+//!   repo; url https://github.com/junegunn/seoul256.vim; genizah ~/05-genizah/seoul256.vim; commit 0357ff3e44faab66c98bc98dfc89c834e37012da
+//! Tags: the window bar (StatusLine / StatusLineNC, or mode-line / mode-line-inactive).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag text #dfdebd -> #12120f: 3.02:1 on #9a7372, tag text needs 4.5:1
+//!   - focused grip #719899 -> #4b6465: 1.31:1 on the focused tag #9a7372
+//!   - rules between panes #e1e1e1 -> #cacaca: 1.31:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)
+//! Upstream notes: g:seoul256_background = 256 (light). Resolved exactly as
+//! ~/05-genizah/seoul256.vim/colors/seoul256.vim:145-177: dark_bg=237,
+//! light_bg=256, dark_bg_2=235 (line 175: dark_bg>233 ? dark_bg-2 : 16),
+//! light_bg_1=256, light_bg_2=256 (lines 176-177, min(..,256)); s:hi uses the
+//! second (light) list element (s:style_idx, line 165) and maps any index >255
+//! to 231 (lines 184-185). GUI hex from the file's default s:rgb_map
+//! (~/05-genizah/seoul256.vim/colors/seoul256.vim:120-135, iTerm2-measured
+//! values; NOT the xterm table, which is only used when g:seoul256_srgb=1,
+//! lines 37-118). The background knob is a fixed integer set: dark 233..239
+//! (default 237), light 252..256 (default 253) (lines 147-150, 169/173;
+//! README.md:52-60); any other value is discarded (line 152) and the style
+//! falls back to &background/colors_name; non-integers are not meaningful
+//! because the offsets index a Dict by integer. StatusLine/StatusLineNC are
+//! gui=bold,reverse so status roles are the rendered (swapped) colours. No
+//! Diagnostic* groups (error/warning from ALE signs, info/hint null). ansi: the
+//! colorscheme sets no g:terminal_ansi_colors/terminal_color_*; ansi is the
+//! repo's own urxvt port, which exists for one background only (253) and is
+//! reused unchanged for every level. Index gaps: for this level the roles
+//! tabline_fg land on an xterm index missing from the default s:rgb_map, so Vim
+//! emits gui*=NONE and they inherit Normal (given as such).
