/* Vantage — vendor pitch. MACHINED INSTRUMENT direction.
   Portillo Technologies: black anodized (#0A0A0A) + warm bone (#E8E5E0) + ONE
   signal red (#C7361E) used only for ARMED / ALERT / SENSING. No gradients, no
   soft drop shadows, no pill badges, no glow dots. Söhne Mono carries every
   status readout and model number (hard brand rule). Reads like operating a
   precision device, not a marketing page.

   Brand fonts (Söhne Breit Halbfett / Buch / Mono) are licensed binaries, not
   bundled. Drop the woff2s into /static/fonts/ and uncomment the @font-face block
   to go pixel-exact; the fallbacks below carry the same intent until then. */
