/* TermPeek blog — post + index layout.
 *
 * Reuses `tokens.css` (imported via base.css, already loaded by every blog page) — dark mode
 * arrives for free via `@media (prefers-color-scheme: dark)` inside tokens.css, same as the legal
 * docs and landing. This file adds only blog-specific structure (site header, article, sources
 * list, CTA, index list, table) on top of the shared tokens.
 */

/* Button — mirrors landing.css `.btn` / `.btn--primary` (tokens-only, same look-and-feel).
 * Not importing landing.css wholesale here: it also carries hero/pricing/nav selectors that
 * don't apply to the blog and would add unused weight. */
