   P&K INDUSTRIES — Cold roll formed steel profiles
   --------------------------------------------------------------------------
   DESIGN NOTES (keep these in mind when editing)

   Palette      Taken from the P&K logo, not invented.
                mill / slab / gauge  = steel greys built on the logo outline
                                       navy-black (#05151C)
                steel                = #6D747C, the grey link in the mark
                amber                = #F6B30A, the gold link and the "P&K"
                                       wordmark. Used in exactly three places:
                                       the formed line in a drawing, the primary
                                       action, and the active state.
                zinc                 = galvanised blue-grey, body text on dark

   IMPORTANT    --amber is a GRAPHIC colour only. At #F6B30A it sits at ~1.9:1
                on white, so it must never carry small text or an icon on a
                light surface. Use --accent-text for anything a person reads:
                it resolves to a darker bronze on light bands and to full amber
                on dark ones. The primary button is likewise amber with
                near-black text, which is both brand-true and legible.

   Type         Archivo   wdth 118   display. Wide, not condensed — a rolled
                                     section seen edge-on.
                IBM Plex Sans        body.
                IBM Plex Mono        dimensions, title blocks, labels. Reads as
                                     drawing annotation.

   Grid texture Only on surfaces that represent a drawing sheet. It is
                information, not wallpaper. Never full-bleed on a section.

   Numbering    Only where the content is genuinely a sequence: forming pass
                stations, and the order of a job. Nowhere else.
