/* ==========================================================================
   SALTIRE SKETCH — DESIGN SYSTEM
   Palette: ink slate, off-white, charcoal, cool architectural grey, verdigris,
   a single restrained Scottish blue used only as a line/accent, never a fill.
   Type: Fraunces (display + nav) + Inter (body, buttons, labels)
   Signature: hand-drawn blueprint elevation that draws itself in on load,
   and architectural "dimension lines" used as section dividers/eyebrows.
   ========================================================================== */
