/* Merkel Technologies — merkeltechnologies.com
   Brand taken from the main site (merkel.co.il): navy #02113D, blue #39539E,
   magenta accent #CC3366, Inter. Instrument-panel feel: cool neutrals, generous
   space, monospace for spec-like labels. No build step, no external requests —
   the whole site is three files and a system font stack. */
