/* ========================================================================== Kettlefinch — editorial design system One stylesheet, no build step, no webfont requests. Structure comes from full-bleed tonal bands and space, never from separator rules. Sections alternate --paper and --band; the footer is a near-black block against the light head of the page. THEME: light is the default; dark is a full repaint of the same tokens. The masthead toggle writes data-theme onto and remembers it; with no stored choice the OS preference wins. No component rule below cares which theme is on — they all read tokens. ========================================================================== */ /* ── Tokens: neutrals (shared by all three palettes) ───────────────────── */ :root { color-scheme: light dark; --paper: #fafaf9; /* page ground */ --band: #f1f2f4; /* alternating section ground */ --band-head: #e9ebef; /* masthead band — a touch firmer than --band */ --sheet: #ffffff; /* panels and inputs */ --ink: #14161b; /* headings, body */ --ink-2: #3c4250; /* secondary body */ --muted: #5c6270; /* meta, labels */ --field-line: #7c8495; /* input border — 3.8:1, clears the UI floor */ --foot-bg: #0a0c10; --foot-text: #e9ebf1; --foot-muted: #9aa3b5; --code-bg: #0a0c10; /* code blocks and the license key */ --on-accent: #ffffff; /* text on an accent fill */ --show-sun: none; /* the toggle shows the theme you would get to */ --show-moon: block; /* Accent: ink blue */ --accent: #1b4bcf; /* links, kickers, marks */ --accent-deep: #143aa0; /* pressed / hover on light */ --accent-lift: #8fb0ff; /* the same accent on a dark ground */ --accent-wash: #e8edfb; /* notice backgrounds */ /* Two alternates that were built and measured alongside this one; swap all four values to change the whole site.
