audit-schema-consumption.md's recurring defect: a key that validates
but does nothing, five separate instances (css/extra.css overlay,
tokens.font_family, tokens.font_fallback, tokens.font_size_base,
tokens.accent_to). All five are consumed only by breadbar/breadbox,
which this pass doesn't touch, so per the audit's own (a)/(b)/(c)
choice this is (b): document the gap at both the schema accessor and
every theme.toml site that sets the key, so the manifest states its
design intent honestly instead of implying the value has an effect it
doesn't.
Also documents modules.clock.format/show_date (consumed only by
ClockStyle::Plain, silently ignored by Flip/None) and
bar.window.margin.bottom (parsed, never applied by breadbar) the same
way.
radius (20 -> 8) and icon_px (36 -> 32) were demo-derived aspirations, not
what breadbox implements today (.launcher-bg's actual border-radius and
make_icon's actual set_pixel_size). row_anim/rule/footer/sections/modes are
kept but marked declared-but-not-yet-consumed: breadbox implements none of
row animation, a rule/divider, a footer, sections, or query modes today, so
the manifest should say so rather than imply they're live. Adds a builtin
launcher test mirroring the existing window/tokens fidelity tests.
Reproduces breadbar's now-removed fixed Lua-widget interleave
(right-of-workspaces, left/right-of-clock, left-of-stats) as explicit
widget: slot entries, so the builtin theme still renders pixel-identical
to today's bar under breadbar's new theme-driven widget placement.
`tray` deliberately has no slot entry anywhere — it stays in the
control-panel popover regardless of [bar.slots].
Updates the one test asserting the builtin's slot contents.
Implements the shell theme manifest layer from THEME_SYSTEM_PLAN.md
§4-5: ShellTheme/WindowSpec/Slots/Tokens/LayerRule types, TOML
discovery (user -> system -> compiled-in builtin), one level of
`extends` deep-merge, deny_unknown_fields validation naming the
offending key, slot module-name validation, and css() token
substitution with an extra.css overlay. load() never fails, falling
back to the compiled-in builtin and logging once.
Ships exactly one builtin manifest, liquid-motion, describing
breadbar/breadbox as they exist today (not the design-doc demo, which
disagrees with the code on bar side margin, launcher geometry, and the
easing curves). Compositor rules and surface specs are keyed by
layer-shell namespace and cover all five breadbar namespaces plus
breadbox/breadbar-panel/breadbar-dismiss.
watch() is gated behind the existing `gtk` feature (gio::FileMonitor
is a gtk4 dependency); the rest of the module is gtk-free so bread and
breadcrumbs can validate a theme without linking GTK. No consumer
changes — breadbar/breadbox still use their own hardcoded values.
