/*
 * Panakoes landing page.
 *
 * Design system mirrored from lafayettelabs.com (the parent LLC's site):
 * paper / ink / signal palette, hairline rules, numlabel section markers,
 * mono caps for utility text, italic serif emphasis inside grotesk display.
 * Fonts: system stack for body copy, plus ONE self-hosted woff2
 * (Inter Tight 800, latin subset, ~22 KB, OFL) used only by the
 * PANA|KOES wordmark so it matches the lafayettelabs.com brand
 * exactly. Still zero external font requests; CSP stays
 * font-src 'self'.

/* The PANA|KOES wordmark is a pre-rendered SVG (assets/images/wordmark.svg)
   with the Inter Tight 800 glyphs converted to outlines, generated by
   scripts/generate-wordmark.py from assets/fonts/inter-tight-800-latin.woff2.
   CSS-typeset versions rendered differently across OS/DPI (baseline and
   padding rounding); outlines are pixel-identical everywhere. The woff2
   stays in the repo as the generation source but is no longer loaded by
   the page. */
