Lantern Trace — visual directions

Linear-style restraint on the current light theme: softer chrome, distinct pass, fail, and access-hold treatment, and the open oxygen row as the only full action set.

iOS Health–style grouped lists with a back control, large title, inset rows, segmented result control on the open outlet, and a full-width Pass Room footer.

Dashboard ledger tables with hairline borders, indigo primary actions, tabular counts, and a left-edge status rail on zone and room rows.

Warm catalog paper with condensed architectural headers and 1960s pigment blocks on gas stubs, terracotta fail slabs, and dashed ochre access-hold slabs.

Primary red, yellow, and blue on a heavy-ruled rectilinear grid with circle, triangle, and square encoding pass, fail, and unable to test.

International typographic grid with monumental orientation numerals, flush-left type, Signal Red for fail, and diagonal hatch for access hold.

Survey-atlas plates on ivory paper with serif masthead, running heads, hairline rules, and corridor-legible verdigris and oxide status chips.

Less-but-better industrial labeling on off-white, graphite ink, fail as a solid bar and unable as outline, with signal orange only on the open row and Pass Room.

Stepped black, brass, and ivory civic frame with incised masthead, one sunburst mark per screen, and solid geometric chips on a flat outlet list.

MUJI-like warm paper and birch-gray rules: the zone as a room register and the room as a completed form with the next blank row isolated.

Civil survey and equipment-log metaphor with mono IDs, carbon stamps, ruled unit register, and tall ledger rows for the next line to fill.

1980s laminate color patches and hard black rules kept to margins and headers while capture controls stay deliberately conservative and tappable.

Poster geometry with a diagonal-cut header slab, parallelogram progress marks, fixed-height result bars, and ochre reserved for the next outlet to test.

Dark electronic flight-bag panels with bone type, dense table rows, desaturated pass and fail hues, and amber only on the untested row and Pass Room.

GOV.UK-style back link, summary table, square black buttons, yellow block on the next room and next outlet, and tags that spell out fail versus unable to test.
