/* TabulaKit shared framework — baseline stylesheet. Served statically (public/) and linked from the Base layout, so it loads deterministically in both dev and build (no reliance on Astro's dev-mode CSS injection, which is fragile inside the embedded preview iframe). A project's customization/theme/theme.css is injected after this and overrides it. One cohesive palette drives two layouts: - portal — top-nav, centered column, frosted header + footer (modeled on tnman-2026-portal) - sidebar — left docs nav with a branded header (modeled on the Mojo docs site, @mojo/static-site-ui) Both share a teal primary (links, active states, brand) and a warm accent (section headings), the common ground between the two references. Light is the default; the toggle (top-right) flips data-theme on and the shell sets the initial value from the Kit's default-preview-theme (TABKIT_PREVIEW_THEME). */ :root { /* color-scheme paints the browser canvas to match, so page-to-page navigation never flashes the wrong background. */ color-scheme: light; --bg: #ffffff; --fg: #1b2330; --muted: #5b6573; --border: #e5e8ec; --surface: #f7f8fa; /* sidebar / header fill */ --surface-2: #eef1f5; /* hover */ --surface-3: #e8edf2; --primary: #1f7078; /* teal — links, active nav, brand */ --primary-strong: #195a60; --primary-soft: #e4f2f3; /* active-nav background */ --heading: #c2410c; /* warm vermilion — h2 + section labels */ --accent-dot: #ea580c; /* portal brand dot */ --code-bg: #f5f6f8; --code-inline-bg: #eef1f5; --shadow-1: 0 1px 2px rgba(16, 24, 40, 0.06), 0 1px 3px rgba(16, 24, 40, 0.08); --radius: 10px; --radius-sm: 7px; --content-max: 820px; --portal-max: 900px; --font-sans: ui-sans-serif, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif; --font-mono: ui-monospace, SFMono-Regular, Menlo, Monaco, Consolas, 'Liberation Mono', monospace; } /* Navy dark theme (tnman-flavored).
