Create a finished horizontal park-trail banner, 3:2 ratio, designed for outdoor wayfinding and readable from distance. Full-bleed dark charcoal-black field (#111417), with a clean centered white rectangular sign panel occupying 86% width and 64% height; no photographic scenery, no trees, no moss, no rust, no distressing, no gradients, no glow, no shadows on letters. At the top of the white panel, centered in small condensed geometric sans caps, set the exact text: "NORTH RIDGE PARK". Beneath it, dominant and centered across two lines, set the exact headline: "TRAIL" then "OPENS MAY". Draw every headline character as custom Elder Futhark-inspired runic angular lettering: tall narrow proportions, pure matte black ink, strict straight segments only at 0, 90, and 45 degrees; absolutely no curves, arcs, rounded corners, texture, bevels, or shading. Replace every normally rounded Latin form with a sharp rune-like angular construction; blade-cut flat terminals and hard vertex junctions. Ensure the wording remains instantly legible in English despite the runic geometry. The headline fills most of the panel, with generous clean spacing and strong vertical rhythm. Below the headline, centered in small crisp geometric sans caps, set: "PLEASE STAY ON MARKED ROUTES". Add two tiny symmetrical angular runic chevrons on either side of this line, black only. Outside the panel, retain a deep charcoal border; across its upper edge, add a very subtle flat cold-northern-light stripe in deep teal and icy blue (#0D5263, #78B9CC), with no aurora, particles, fire, or organic texture. Flat screen-print-ready vector composition, maximum contrast, exact spelling, disciplined park-sign hierarchy.
