/* =====================================================================
   pg-features2.css: extras for the Features hub + AI inbox assistant, AI reply drafts, Ask Scrubbr
   (features/index.html, ai-inbox-assistant.html, ai-email-drafts.html, ask-scrubbr.html) on tpl.css.
   Load order: styles.css -> tpl.css -> section-footer.css -> pg-features2.css. Everything is namespaced .pfa-*.
   The UI snippets are static, aria-hidden sample data: the same people and messages as the home product panel.

   PAGE RECIPE (feature page): hero (pill, h1, sub, two start buttons, fine print) + framed .tp-mock
     -> "Works with" strip (.tp-logos, white sheet)
     -> "How it works": .pfa-splits, 4 alternating split rows (text left/right, UI snippet in .pfa-viz)  [mint]
     -> "What it covers": .tp-cards with .pfa-tile icon chips (3 or 2 columns)                          [white sheet]
     -> "Who it is for": .pfa-who three plain columns                                                    [mint]
     -> privacy: .tp-fold.tp-callout (two paragraphs)                                                    [white sheet]
     -> related features: .tp-links                                                                      [white]
     -> FAQ (.tp-faq, tp-soft) -> closing CTA (.tp-cta) -> footer.
