[BRAND NAME]. Act as a Senior Industrial Designer and Technical Illustrator, specializing in pencil engineering sketch reproductions of brand logos (style: hand-drawn technical blueprint/concept sketch on aged paper). PHASE 1: AGED PAPER SURFACE A warm, aged beige-cream paper surface (#E8D5B0 range) filling the entire frame — with visible aging spots, worn patches, scattered pencil smudges, and fine paper grain consistent with a real old technical sketchbook or archival drawing sheet. Subtle vignette darkening at all frame edges. No clean digital white — the paper must read as genuinely old and physical. PHASE 2: LOGO RECONSTRUCTED AS PENCIL TECHNICAL SKETCH (TRUE SHAPE) [BRAND NAME]'s real, official primary icon/logomark is reproduced with full shape and proportional accuracy exactly as it appears in the brand's real guidelines, then rendered entirely as a hand-drawn pencil engineering sketch — as if a designer sketched the logo concept by hand in a technical drawing session. The logo is positioned in the center of the frame, occupying roughly 40–50% of frame height. CRITICAL ACCURACY INSTRUCTION — NON-NEGOTIABLE: Do not invent, approximate, restructure, or substitute the logo with any other imagery. The logo's real geometry and proportions stay exactly as in the brand's real guidelines — only the pencil sketch rendering treatment is applied on top of the unchanged shape. PHASE 3: PENCIL SKETCH TECHNIQUE (HERO EFFECT) Two distinct pencil layers build the complete illustration: - CONSTRUCTION LAYER (light pressure): thin, precise straight lines forming a rectangular bounding box around the logo's outer dimensions, plus internal diagonal construction/guide lines radiating from key structural points of the logo — all drawn with light pencil pressure, slightly imprecise, with the natural slight waviness of a hand-drawn straight line. - LOGO LAYER (heavier pressure): the logo's actual forms drawn with firmer pencil pressure — clean but hand-drawn contour lines tracing the real logo shape, with dense diagonal crosshatch pencil shading filling the solid/dark areas of the logo to imply volume and depth. Shading direction is consistent (45-degree diagonal strokes), varying in density from light to dark across the form. PHASE 4: TECHNICAL ANNOTATIONS Around the logo, hand-drawn engineering dimension annotations in classic technical drawing style — rendered in thin pencil handwriting: - Horizontal and vertical double-arrow dimension lines with end caps, indicating key measurements (written as plausible dimensions: "L=Xmm", "R=Xmm") - Angle annotations for key diagonal elements (e.g. "10°", "OFFSET X°") - All annotation text in a clean, slightly imperfect hand-lettered technical style — not a printed font, but the careful handwriting of a technical draftsman - 4–6 annotation labels total, positioned logically around the bounding box and key logo elements PHASE 5: COMPOSITION Logo and annotations centered in the frame with generous aged-paper negative space surrounding them, especially above and below. No color, no additional graphic elements — strictly monochrome pencil on aged paper. TECH SPECS: Flat 2D pencil illustration, no 3D, no digital gradients — all tone from pencil pressure and crosshatch density. Monochrome: dark graphite pencil on warm aged paper. Resolution: 8K.
