/* Truckvisor blog — the post + index surface.
 *
 * Tokens are the landing page's .tvl set (apps/web/src/landing.css) verbatim, with ONE deliberate
 * difference the founder signed off on (2026-09-03): the landing page is night-locked, the blog
 * follows the reader's own device. A blog post is read by a stranger arriving from a search
 * result, often for several minutes — that is the one surface where their preference beats ours.
 * The Day/Night control still overrides, and sticks (localStorage) across posts.
 *
 * Written by hand, inlined into no page: scripts/build-blog.mjs copies it to /blog/blog.css so the
 * browser caches it once for every post.
