Night Shift four-ink gig poster

{
  "style_name": "Night Shift Prints",
  "style_slug": "four-ink-halftone-gig-poster",
  "canvas": "4:5 portrait, full bleed, aged bone paper #E8E0CC as the base layer",
  "color": {
    "inks": ["paper bone #E8E0CC", "ink black #141210", "scarlet #DC1C21", "chrome yellow #F3CF06"],
    "hard_rule": "FOUR flat inks plus paper — no midtones, no gradients, no browns or greys; every pixel resolves to one of the four or to bare paper",
    "overprint": "where black lands on yellow or red it goes fully opaque; slight misregistration offsets of 1–3px are wanted"
  },
  "image_treatment": {
    "portrait": "high-contrast threshold + coarse halftone dot screen in black; skin, fabric and metal all rendered as dot density, never tone",
    "framing": "tight, subject from the waist or chest up, mid-task, hands and tool prominent, eyes down on the work or narrowed in concentration",
    "casting": "working people of visible age and wear — this style needs faces with texture in them",
    "environment": "reduced to flat black or red silhouettes in the negative space — subway columns, water tower, cranes, skyline, antennas"
  },
  "graphics": {
    "red_shape": "one large flat scarlet form behind the head acting as a spotlight — full circle, angular slab, or rectangle field",
    "yellow_marks": "flat diagonal bars or rays with rough dry-brush edges, plus 1–2 loose hand-drawn loop scribbles spiralling across the frame",
    "extras": "sparse halftone dot clusters, tiny arrows, numbered markers, constellation or diagram fragments"
  },
  "typography": {
    "title_band": "a full-width chrome-yellow band across the bottom third; two words set in very heavy condensed black gothic caps, scaled so the first and last letters are cropped by the frame edges",
    "sub_line": "one hand-lettered line under the band — shift / channel / batch / session plus a two-digit number, split by a slash",
    "glyph": "one small hand-drawn mark beside the sub-line: spiral, concentric target, hexagon, lightning bolt",
    "rules": "thin double or triple yellow-and-red hairlines above the band"
  },
  "texture": "heavy paper grain, ink cracking and starve, scratches, dust specks, edge wear — the print should look 40 years old and pulled by hand",
  "design_rules": [
    "the title band always bleeds edge to edge and the type is always cropped",
    "one red shape only, one scrawl gesture only",
    "the subject must be mid-action, never posed",
    "keep it night: every sub-line names a late hour, a shift, or a session"
  ],
  "swap_variables": {
    "trade": "street drummer / radio operator / rooftop beekeeper / night mechanic",
    "title": "CITY BEAT / OPEN SIGNAL / HIVE MIND / FULL TORQUE",
    "red_shape": "halo circle / angular slab / rectangle field",
    "glyph": "spiral / target / hexagon / bolt",
    "sub_line": "NIGHT SESSION 02 / CHANNEL 08 · ALL NIGHT / ROOFTOP BATCH 07 / SHIFT 04 · OPEN LATE"
