Not -# deduplicated against palette/semantic/neutral_button/graph_node even where a -# value happens to coincide - same convention this table already uses -# elsewhere (palette.selection == semantic.default in every theme): group by -# original consumer, not by value, since a numeric coincidence today isn't a -# design relationship the two should be forced to keep in sync tomorrow. -# -# That coincidence is NOT rare, and is worth naming precisely rather than by -# one example: measured directly against the values below, 7 "qss" entries in -# dark, 7 in muted, and 19 in mono also equal some palette/semantic/ -# neutral_button/graph_node value. Mono's cluster is the one to look at -# skeptically before trusting "coincidence" going forward - e.g. mono's -# qpushbutton_hover__background_color, qmenu_item_selected__background_color, -# and neutral_button.hover/.border all sit on #666666, and three unrelated -# selection-background properties (QLineEdit/QTextEdit/titlebar-button hover) -# all equal neutral_button.pressed's #4A4A4A - consistent with mono having -# originally been hand-authored from a small shared gray ramp rather than -# fully independent per-rule choices. Unlike the graph_node/neutral_button -# case above, nothing in the pre-refactor source computed one from the other -# for any of these pairs (verified: the original hand-written QSS and -# get_neutral_button_colors() were always two independent literals, even in -# mono), so leaving them as independent "qss" entries is still the correct -# call today - not a shortcut. It's flagged this explicitly so a later -# Tailwind/schema-codegen pass evaluates promoting some of mono's overlaps to -# real derivations on purpose, instead of rediscovering the pattern cold. -# -# The frame-color presets (DARK_FRAME_COLORS etc. below - ColorPalette.FRAME_COLORS -# reads those dicts directly, not this table) remain out of scope. This grouping -# (palette/semantic/neutral_button/graph_node/qss/qss_alpha) mirrors the -# functions/consumers that existed before this table did, kept as-is here to -# keep changes byte-identical and reviewable - it is not the target shape a -# later Tailwind/schema-codegen pass will want (see the master plan's flatter -# token list) and should be expected to be reshaped, not just extended, when -# that work starts. -# -# "graph_node" intentionally holds only its 6 members that are independent -# theme literals (body_start/body_end/header_start/header_end/badge_fill/ -# panel_fill). The other 7 keys get_graph_node_colors() returns -# (border/header/dot/hover_dot/hover_outline/selected_outline/panel_border) -# are not independent tokens - they are aliases of, or QColor.lighter() -# derivations from, get_neutral_button_colors()'s output (this is exactly -# what the pre-this-table branching logic computed). Storing those 7 as their -# own flat literals here would silently drift from neutral_button the next -# time someone edits a theme's button colors without also updating 7 more -# entries by hand; get_graph_node_colors() below derives them live instead. -# Composer island chrome colors, captured verbatim from -# web_ui/src/islands/composer/styles.css, where they were hand-authored as -# literal hex/rgba with their own eyeballed dark palette - never derived from -# any theme this app actually ships (section 2's own survey already flagged -# this: "styles.css hardcodes its own dark hex values"). -# -# Split flat/alpha on exactly the qss/qss_alpha precedent: the rest of this -# table has no representation for partial-alpha colors, and composer uses 18 -# rgba() literals for borders, overlays, focus rings and drop shadows. -# -# These two dicts are the SINGLE source of the values; the per-theme groups -# below are built from them with dict(), so the same 43 values are not -# triplicated by hand across three themes. That construction is deliberate and -# load-bearing in both directions: the per-theme SHAPE is real (a future -# increment authoring a genuine mono or muted composer palette edits one line -# per theme, with no restructuring), while the shared VALUES record the honest -# fact that composer has only ever had one palette. Storing identical values -# across themes is not a new shape here - graph_node is already byte-identical -# between "dark" and "mono" across all six of its keys (verified, not assumed). -# -# Naming is per-OCCURRENCE, not per-value: 43 tokens for 34 distinct colors. -# That follows this table's own "group by original consumer, not by value" -# rule (see the comment above), and needs no interpretation - e.g. -# status_text/status_failed_text hold the same #b0b0b0 at two different CSS -# sites, so the fact that .request-status.failed's override is currently a -# no-op stays visible in the data instead of being silently collapsed away. -# The one genuinely interpretive act, flagged rather than buried: composer's -# two box-shadow declarations each carry two colors (a drop shadow plus an -# inset highlight / focus ring), a case qss_alpha never hit, so those four got -# explicit part suffixes (*_shadow_drop / *_shadow_inset / *_focus_ring). -# -# Keys use SINGLE underscores, unlike qss's "__" property-separator -# convention - a double underscore would emit "--gl-composer-shell--background", -# which fails the CSS custom-property name shape the tests already enforce. -# -# DERIVED RELATIONSHIPS THAT PER-OCCURRENCE NAMING DOES NOT ENCODE. Read this -# before authoring a real per-theme palette - flat capture necessarily discards -# these, and nothing below will fail if they are broken: -# -# attachment_count_border MUST TRACK shell_background. The badge is -# position:absolute at top:-5px/right:-7px on a 30x30 control, so it overhangs -# its button and sits on the shell. Its 1px border is exactly the shell color -# because it is a cut-out/halo punching the badge visually out of the shell - -# not a border color chosen for its own sake.

What this prevents is the ergonomic default: minting -# bg-gl-composer-* utilities that make reaching for another island's private -# chrome the path of least resistance. css_custom_properties()'s docstring is -# already honest about the same limitation for the mechanical names. -# -# When a SECOND island lands here, that is the first time there are two real -# examples to generalize a shared semantic vocabulary from - the release -# condition css_custom_properties()'s docstring names for the deferred -# bg-0/1/2-style naming. That check lives in tests/test_theme_tokens.py rather -# than as a module-level assert here, deliberately: an import-time assertion -# would make graphlink_styles unimportable and take the whole app down mid- -# feature, which punishes the developer who followed the convention and -# registered their island here, while the developer who instead added it to -# css_custom_properties()'s included_groups would never trip it at all.
