/*
  File: css/portfolio.css
  Purpose: Page styles for /portfolio (Views/public/portfolio.php, "Our Work")
           — the framing-stage photo hero (swaps the .wrapper2 band photo via
           [data-page="portfolio"]), the centred intro, the two-column layout
           (project-card grid + the filter SIDEBAR <aside class="work-side">,
           a sticky card like the blog's Categories box: list of options with
           counts, pressed state = aria-pressed written by js/portfolio.js, and
           a back-to-top link). At ≤1000px the same aside becomes the FIXED
           BOTTOM DOCK: a "Filter · <current>" toggle that opens the option
           list as a pop-up sheet above the bar (data-open on the aside) plus
           a round back-to-top button; the page and the footer pad their
           bottoms so nothing hides behind it. Cards: photo on an inner
           clipping wrapper, category chip, title, excerpt, arrow link;
           data-visible / data-empty filter states and the empty message.
           Replaces the horizontal carousel + inline <style> block the page
           carried until 2026-09-13. Motion = the shared [data-reveal] scroll
           reveal (states in css/site-shell.css, js/site-reveal.js). Loaded
           through layouts/public's renderSection('head') after
           bootstrap-4.4.1.css, main.css and site-shell.css, so every rule
           restates font/size/spacing and every class is prefixed work-.
           Design tokens (--band, --teal, --line, --display, --serif …) come
           from css/site-shell.css; the tall hero band is
           .banner3[data-hero="tall"] in css/main.css.
  Used by: Views/public/portfolio.php (via <?= $this->section('head') ?>)
