/* ==========================================================================
   stockery — landing page (ROOT Stok)
   Built on the posi design system. Monochromatic core; a single restrained
   ACCENT (green) appears only as brand "sparks" and interactive elements —
   never as a stock-status color. Stock states have their own dedicated
   palette (kırmızı/amber/nötr), mirroring the actual product's own rule:
   "healthy stock gets no color at all."
   Copy is Turkish throughout — lowercase by house voice, so nothing ever
   needs a CSS uppercase transform (which mangles Turkish dotted/dotless i).
