/*
 * Long Swedish compound words (robotgräsklippare, jämförelsetabell,
 * specifikationsguide…) overflow or break mid-word with no visible hyphen
 * at narrow (390px) widths otherwise. `hyphens: auto` needs a language on
 * the element/ancestor to pick the right dictionary — header.php already
 * outputs `<html lang="sv-SE">` via language_attributes(), which is enough,
 * but headings also declare it explicitly so hyphenation still works if a
 * heading's markup is ever lifted out of the document (e.g. copied into an
 * SVG/og-image render or a future syndication feed).
 *
 * Visual QA confirmed `hyphens: auto` is
 * correctly configured (lang is right, the property computes to "auto")
 * but does not visually hyphenate in this project's headless-Chromium
 * screenshot tooling — a known class of headless-browser limitation
 * (missing ICU/Minikin hyphenation dictionary), flagged as
 * needing live verification in a real browser. Confirmed live: "Slinglösa robotgräsklippare" breaks to
 * a bare "robotgräsklip" / "pare" line split with no hyphen at 390px.
 * `overflow-wrap: anywhere` (up from `break-word`) is the more aggressive
 * fallback the brief asks for — it lets the layout engine consider a
 * mid-word break a valid line-break opportunity everywhere (not only as a
 * last resort), which in practice moves the break to a less awkward point
 * and keeps min-content sizing sane for headings placed in narrow flex/grid
 * contexts. Combined with the narrower h1 clamp below, this is a rendering
 * safety net for environments without hyphenation, not a replacement for
 * `hyphens: auto` (kept — real browsers with the sv dictionary still get a
 * proper hyphen).
