/* ═══════════════════════════════════════════════════════════
   atalayaygul.com — "Signal" theme
   A technical-report look: Swiss grid, ink on paper, one signal colour.
   Light by default, dark when the OS asks for it. No inline styles anywhere
   (the CSP in _headers is style-src 'self'), so chart widths are classes.
   Fonts: IBM Plex Sans (variable, wght 400–700) + IBM Plex Mono 400/500,
   subset to Latin + Turkish + arrows (SIL OFL 1.1, see fonts/OFL-IBM-Plex.txt).
