/* danimelich.com — v4
 *
 * v4 answers Dani's review of v3, plus the editorial-layout lesson: an
 * asymmetric grid — one wide reading column and one narrow margin column — is
 * the standard solution to both "pin the contents to the right" and "there is
 * unused real estate". The margin column is not decoration; it holds the index
 * on a case study and the availability facts on the overview.
 *
 * What came back from v2, because Dani preferred it: the two-line tab (kicker
 * over serif label), the wash under the header, and the wider reading column.
 * What did NOT come back: the contrast failures those things shipped with. The
 * kickers were 2.36:1 at 10px; they now read at 11.5px and pass.
 *
 * The palette is no longer one orange. Each section owns a hue, set by
 * body[data-section] and consumed through --accent / --accent-ink, so the site
 * changes character as you move through it without any page becoming noisy.
 *
 *   1. tokens + palette   2. field   3. masthead + tabs   4. sheet + grid
 *   5. overview   6. document   7. index   8. tables + figures   9. chrome
