"Chip and Coolant" 是一个数控加工频道的介绍卡，采用抛光铬金属风格。频道名用亮闪闪的液态铬金属大字叠放在一台旋转的数控主轴前，主轴溅出火花和金属卷屑，上方一行频道小字，下方一句口号，右边一个圆形每周更新小徽章。

Create a 16:9 YouTube channel banner / key art for a CNC machining channel. Exact rendered text, with clear hierarchy: small upper line: “CNC MACHINING CHANNEL” main title, two centered lines: “CHIP” / “AND COOLANT” small lower line: “PRECISION CUTS • SHOP FLOOR STORIES” small circular stamp at lower right: “NEW BUILDS WEEKLY” Composition: a dark CNC machine interior seen straight-on, with a matte charcoal machine bed and a large steel end mill entering from the upper right, stopping behind the headline; curled silver chips spiral across the lower third, with a narrow stream of translucent coolant catching light. Keep all text unobstructed. Main title occupies 72% of canvas width, centered from 28% to 67% height. The two small support lines are crisp, widely tracked technical sans lettering, flat cool-white steel ink. Design “CHIP AND COOLANT” as custom fluid-metal display lettering: very heavy wide uppercase skeleton, compact spacing, rounded convex stroke shoulders, smooth sealed counters, terminals tapering into tiny gravity-pulled teardrop tips. The letters are formed from mirror-silver liquid mercury, not painted chrome: bulging high-surface-tension contours, continuous reflective white-to-deep-grey environmental gradient flowing across each face, thin liquid seams and subtly pooled lower curves. Deep 3D extrusion, bevel planes with tight bright edge compression. A wide cool key light from upper left creates long smooth silver highlight bands; warm amber machining sparks near the lower right reflect as small gold streaks in the shadowed letter faces. No flat grey fills. Background: deep charcoal fading to steel blue, faint airborne coolant mist, sparse metallic dust, dim industrial depth. Use ray-traced reflections, anisotropic brushed-steel grain on the end mill and machine bed, physical shadows beneath the title, high contrast, precise clean edges. Keep a safe 7% margin around the canvas. No extra text, no logos, no people.
