STYLE REFERENCE — HARD CONSTRAINT (HIGHEST PRIORITY)

This style must be applied to ALL generated content (text, image, video).
If any part of the request conflicts with this style, the style OVERRIDES the request.
STYLE DEFINITION (to be operationally enforced):

White-Line Blueprint Drafting

 • Output Format: Creative discipline: Graphic design; Print; Poster-scale; Canvas Behavior: Strict frame (nothing escapes).
 • Container / Boundary: Container: Explicit (shape mask); Container shape: Card; Sharp Corners; Container Dominance: Neutral frame; Padding: 10% white background surrounding the card; Edge Behavior: Content fully contained.
 • Mood & Personality: Clean, Serious, Authoritative, Industrial, Documentary realism; Energy: Steady; Representation mode: Literal; Real-world accuracy: Precise.
 • Colors: Palette: Solid Colors: [ #003B6F 90% (Duotone: Ground),  #F5FAFF 10% (Linework)]; Duotone; Cool temperature; Saturation: Rich; High contrast; No gradients; Color dominance: Background-dominant.
 • Typography: Single-stroke drafting lettering; Regular; Text case: ALL CAPS; Font pairing: Single family; Hierarchy: Subtle contrast; Normal (1.4); Letter spacing: Wide; Text presence: Required; Text visual role: Secondary visual element; Text integration: Embedded in shapes.
 • Light & Shadow: Lighting presence: None (flat); Shadow type: None.
 • Spatial Structure & Hierarchy: Flat perspective; Multiple equal focal structure; Hierarchy: Strong; Symmetry: Asymmetrical balance; Balance: Evenly distributed; Layout axis: Gridless; Grid system: Engineering-sheet orthographic layout; plan, elevation, section, and detail views positioned by drafting convention; Visual density: Balanced.
 • Surface, Material & Detail: Material simulation: Paper; Surface treatment: Matte; Texture: Subtle cyanotype coating mottling, pale edge falloff, fold rub, pinholes, and slight line bloom; Texture usage: Subtle noise; Imperfection level: Used; Age of surface: Aged; Micro-detail allowance: Allowed.
 • Shape Language: Geometric; Primitive dominance: Rectangles, Circles, Polygons; Edge sharpness: Razor-sharp; Silhouette clarity: Recognizable; Negative space usage: Balanced; Angle usage: Frequent.
 • Line & Stroke System: Structural outlines; Variable; Strict hierarchy: heavy cut edges, medium visible outlines, thin dashed hidden edges, long-short chain centre lines consistency; Stroke Color: Contrasting accent; Stroke joins: Miter.
 • Background & Environment: Background type: Solid color; Background–Subject: Integrated; Background complexity: Minimal.
 • Artistic Mediums & Techniques: Physical medium: Cyanotype; Illustrative technique: Orthographic technical drafting; 45-degree section hatching; dimensioning and keyed detail callouts.
 • References: Cyanotype blueprint, nineteenth- to mid-twentieth-century engineering drawing convention; Temporal reference: Mid-nineteenth century to mid-twentieth century.
 • Guardrails: Avoid: AI Gloss / Plastic Smoothing, Heavy Bokeh / Blur, Lens Flare, HDR over-processing, Over-saturation, Studio Post-processing, Stylistic filters; Avoid Visuals: blue line on white ground; sci-fi interface graphics; glowing lines; scan-lines; photographic backgrounds; tonal shading; isometric views; coloured faces; parallelogram shadows; engraved scientific illustration; Avoid Colors: multicolour palettes; gradients; tonal midtones; neon cyan glow; Avoid Layouts: administrative specification-sheet layouts; pictorial composition; floating text; unruled typography; Allowed Visuals: high-contrast pale linework; saturated ground; ruled inset border; lower-right title block; extension lines; arrowheads; 45-degree hatching; dashed hidden lines; chain-dashed centre lines; circled detail callouts; optional red revision marks.
 •  Drafting Sheet Structure: Inset ruled border; lower-right title block with drawing number, scale, date, drawn-by, and revision; revision table stacked above when needed., Dimensioning Logic: Dimensions sit outside objects on thin extension lines; arrowheads at both ends; numeral breaks the dimension line at midpoint., Section Convention: Every cut section receives evenly spaced 45-degree hatching; solidity is never described with shading., Type Placement: Short, letterspaced labels and numerals only; contained within title-block cells, dimension breaks, or circled detail bubbles., Enamel Pin Translation: Use a hard-enamel-like, saturated ground with recessed pale technical linework, raised metal-style borders, and simplified legible drafting symbols..


ENFORCEMENT RULE: Before finalizing the output, internally verify that ALL elements comply with the style definition above. If compliance is uncertain, simplify or soften the output until it fully matches the style. Generated by StyleRef.io
