/* Strome Engineering Corporation — site styles, rebuilt 2026-10-18 on the wordmark kit (Logo Guide r2).
   Ground: paper. Text: ink. One accent: steel, in small doses. Display type: Barlow Semi Condensed, the logo's face,
   self-hosted from the kit (SIL OFL). Body: the visitor's system sans, so no font request leaves the page.
   The vernacular is the drawing sheet: thin rules, square corners, a title block. Always light. */
