/* =============================================================
   Hearthline Press — storefront stylesheet
   Implements brand-guidelines.md v1.0 (2026-07-10)
   Revised 2026-07-11 per research/improvement-research.json
   ("landing-design" recommendations): 19px body for 40–65 eyes,
   larger h1, no umber below 0.9rem, bigger tap targets, stat
   strip, guarantee lines, CSS printed-page mockups, testimonial-
   ready review block, sources fine-print block, bundle card.
   Palette: Warm Paper #FAF6F0 · Hearth Ink #3B322C · Worn Umber #6B5F55
            Soft Sand #E4DACB · Field White #FFFFFF
   Accents: Sage (Binder) · Slate Blue (Playbook) · Clay (Command
            Center) · Ochre (mini-SKUs / lead magnets)
   Type:    Literata (headings) / Source Sans 3 (body), self-hosted
            latin woff2 subsets in ./fonts/ — no CDN requests.
            Revised 2026-07-14 (brand v1.1 pilot): Literata replaces
            Lora for headings (bookish warmth, less template-default);
            paper-grain texture overlay added (anti-flat pass).
