   D. Samuel — Instructional & Learner Experience Design
   Portfolio site stylesheet  ·  "Forest & Stone" theme
   ============================================================

   ARCHITECTURE
   ─────────────────────────────────────────────────────────────
   This is the SINGLE shared stylesheet for every page on the
   site:  index.html, work.html, about.html, writing.html,
   contact.html, and all three essay pages.  All pages link to
   this file so design tokens and components stay consistent.
   No page-specific CSS files exist — everything lives here,
   organised into clearly marked sections.

   DESIGN SYSTEM SUMMARY
   ─────────────────────────────────────────────────────────────
   Palette:  Forest & Stone — warm sand backgrounds, deep
   evergreen greens, antique brass accents.  Intentionally
   avoids red/orange and near-black (#000 / #111) panels that
   felt too stark on the original Wix site.

   Typography:
     Display  — Fraunces (Google Fonts, variable optical size)
                Used for headings, pull quotes, brand name.
                Italic variant gives expressive contrast.
     Body     — Hanken Grotesk (Google Fonts)
                Clean, modern sans — readable at small sizes.

   Accessibility:
     • All text/background color pairs meet WCAG 2.1 AA (4.5:1
       for normal text, 3:1 for large text).
     • prefers-reduced-motion block strips all animations for
       users who need it.
     • Focus styles are preserved (browser defaults) on all
       interactive elements.

/* ============================================================
   1. CUSTOM PROPERTIES (design tokens)
   ─────────────────────────────────────────────────────────────
   Every color, font, shadow, and layout constant is defined
   here as a CSS custom property so changes propagate to the
   entire site by editing one value.

   COLOR RATIONALE
   • --sand / --sand-deep / --cream  — three slightly different
     warm neutral backgrounds.  sand = page base, sand-deep =
     alternate-banded sections, cream = cards & form panels.
   • --ink / --ink-soft / --ink-muted — warm near-black text
     in three weights.  ink = headings, ink-soft = body copy,
     ink-muted = labels, meta, captions.
   • --evergreen / --evergreen-d  — primary forest green.
     Used for the brand accent, nav underlines, active states,
     CTA button backgrounds, and section borders.
   • --panel  — deep forest, used for the sticky skills panel
     and footer background.  Chosen instead of pure black to
     stay warmer and on-brand.
   • --terracotta / --brass-d  — antique brass/gold accent.
     --terracotta is safe on dark surfaces (the panel, footer)
     and large display uses.  --brass-d is the darker, AA-safe
     version for small text on light backgrounds.
   • --line  — hairline borders.  Warm tan so borders feel
     like paper, not cold grey.
   • --shadow  — layered, warm shadow with slight vertical
     offset.  The long negative spread creates a natural glow
     without an obvious hard edge.
   ============================================================ */

   2. RESET & BASE
   ─────────────────────────────────────────────────────────────
   Minimal reset — zero margins/padding, border-box sizing
   everywhere.  No normalize.css or full reset library is used;
   the goal is to stay lean and predictable.

   body::before injects a subtle SVG noise texture (grain)
   across the entire viewport, fixed so it doesn't scroll.
   pointer-events: none ensures it never intercepts clicks.
   opacity 0.04 keeps it near-invisible — adds depth without
   distraction.
   ============================================================ */
* { margin: 0; padding: 0; box-sizing: border-box; }
html { scroll-behavior: smooth; }
body {
  font-family: var(--font-body);
  background: var(--sand);
  color: var(--ink);
  line-height: 1.6;
  -webkit-font-smoothing: antialiased; /* sharper text on macOS Chrome/Safari */
  overflow-x: hidden;                  /* prevents horizontal scroll from portrait ring animation */
}

/* Text selection — uses brand colors for a polished feel */
::selection { background: var(--evergreen); color: var(--sand); }

a { color: inherit; text-decoration: none; }
img { display: block; max-width: 100%; }

/* .wrap — reusable max-width container centered with side padding */
.wrap { max-width: var(--maxw); margin: 0 auto; padding: 0 32px; }

/* Grain / atmosphere overlay — SVG fractal noise embedded as a data URI.
   Fixed so it doesn't scroll with the page.  Gives the sand background
   the subtle texture of paper or stone rather than flat color. */
body::before {
  content: ""; position: fixed; inset: 0; z-index: 1; pointer-events: none;
  opacity: 0.04;
  background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='120' height='120'%3E%3Cfilter id='n'%3E%3CfeTurbulence type='fractalNoise' baseFrequency='0.85' numOctaves='3'/%3E%3C/filter%3E%3Crect width='100%25' height%3D'100%25' filter='url(%23n)'/%3E%3C/svg%3E");
}


/* ============================================================
   3. NAV
   ─────────────────────────────────────────────────────────────
   Sticky top navigation with a frosted-glass effect.
   • position: sticky + z-index: 100 keeps it above all content.
   • The transparent border becomes visible (--line color) once
     the user scrolls down 12px — site.js adds the .scrolled
     class at that threshold.
   • backdrop-filter: blur(10px) + semi-transparent background
     creates the frosted glass look without hiding underlying
     content completely.
   • Active state: the current page's nav link receives
     class="active" on the <a> element.  It gets a full-width
     underline and full --ink color.  Each HTML file sets this
     on its own corresponding link.
   • Mobile: the .nav-links flex row turns into a fixed
     dropdown slide-in panel at ≤900px (see responsive section).
     The hamburger button (#navToggle) is hidden on desktop,
     shown on mobile via media query.
   ============================================================ */
header.nav {
  position: sticky; top: 0; z-index: 100;
  background: rgba(239,233,221,0.82); /* --sand at 82% opacity for frosted effect */

   4. BUTTONS
   ─────────────────────────────────────────────────────────────
   Two button variants used on hero and closing CTA sections:
   • .btn-primary  — filled evergreen (primary action)
   • .btn-ghost    — outlined dark (secondary action)
   Both share the .btn base class which handles layout,
   padding, border-radius, and the arrow nudge animation.
   ============================================================ */
.btn {
  display: inline-flex; align-items: center; gap: 10px;
  font-weight: 600; font-size: 0.98rem; cursor: pointer;

/* ============================================================
   5. HERO (home page — index.html only)
   ─────────────────────────────────────────────────────────────
   Two-column grid: text content (left, 1.15fr) + portrait (right, 0.85fr).
   The grid collapses to single-column on mobile (see responsive section).

   PORTRAIT / HEADSHOT
   The <img> inside .portrait has an onerror handler that hides
   itself and shows the monogram fallback ("DS") if headshot.jpg
   doesn't exist.  To add a real photo, drop a file named
   "headshot.jpg" in the donteisha-portfolio folder.  No other
   code changes are required — the fallback hides automatically.

   DASHED RING ANIMATION
   .portrait-wrap::after draws a dashed circle slightly larger
   than the portrait and slowly rotates it via @keyframes spin
   at 60s per revolution.  It's a subtle ambient motion that
   adds life without being distracting.  prefers-reduced-motion
   removes it entirely.

  10. WORK (work.html project list)
   ─────────────────────────────────────────────────────────────
   Each project is an <article class="project"> using a
   3-column grid:  project number | content | CTA link.

   LAYOUT NOTES
   • 88px left column holds just the italic project number (.pnum).
   • Middle column stretches to fill — holds the title, tags,
     and the PAO (Problem / Approach / Design rationale /
     Success measures) detail grid.
   • Right column (auto width) holds the "View →" link.
   • On hover, the entire article nudges right (padding-left: 12px)
     for a subtle interactive feel.

   PAO GRID (.pao)
   Each PAO row is a 2-col grid: label (128px) + value.
   Labels are uppercase brass, values are --ink-soft.
   This aligns all four data pairs into a clean table-like layout
   without using an actual <table>.

   TAGS
   .tag       — base tag chip (evergreen tint)
   .tag.concept — brass/gold tint with ✦ prefix, identifies
                  this as a concept/coursework project rather
                  than deployed production work.  Honesty-first
                  framing so recruiters have full context.

   "VIEW" LINK
   The .view link opens the PDF in a new tab (target="_blank").
   rel="noopener" is set for security (prevents the opened page
   from accessing the opener window via window.opener).
   The arrow slides right on the parent article :hover.

   RIGHT — .skills-panel: sticky dark sidebar with skill chips

   MISSION / VISION CARDS
   Each .vm-card is a cream-background card with a 4px left
   border in --evergreen, giving a subtle accent stripe.
   The h4 inside uses Fraunces italic for editorial warmth.

   SKILLS PANEL
   Background is --panel (deep forest) for visual separation.
   position: sticky keeps it in view while the user scrolls the
   mission/vision cards.  On mobile (≤900px) the sticky is
   removed (position: static) so it flows naturally.
   The .skill-group .gl label is uppercase brass — same visual
   language as the section kicker labels.
   Each .chip has a semi-transparent border that brightens
   on hover for subtle interactivity.

   RESUME LINK
   Currently points to href="#" — update this to the actual
   resume PDF path once the file is available, e.g.:

  12. WRITING LIST  (writing.html + essay "more writing" rail)
   ─────────────────────────────────────────────────────────────
   writing.html uses .essay-grid — a 3-column card grid.
   Each essay page ends with a .more-writing section that
   uses .more-grid — a 2-column grid linking to the other essays.
   Both grids use the same .more-card component.

   MORE-CARD
   The entire card is an <a> tag so the whole surface is
   clickable — no nested buttons or extra JS needed.
   Cards lift on hover (translateY -5px + shadow) for a
   tactile effect.  The arrow inside .read slides on card hover.

  13. CONTACT (contact.html)
   ─────────────────────────────────────────────────────────────
   Two-column grid (1fr / 1fr):
   LEFT  — intro paragraph + clickable email address
   RIGHT — the contact form

   FORM
   • Background: --cream, rounded 20px corners, 1px --line border.
   • .frow splits the first row (First / Last name) into two columns.
   • All inputs and textareas share the same padding, border-radius,
     and focus style (border turns --evergreen on focus).
   • The submit button spans the full form width.
   • The onsubmit handler in the HTML prevents default form
     submission (no backend connected) and changes the button
     text to a confirmation message — a front-end UX courtesy
     so the user knows their message was "sent".

   NOTE: To wire this form to a real email backend, replace the
   inline onsubmit with a fetch() call to a service like
   Formspree, Netlify Forms (when back on Netlify), or EmailJS.

  16. REVEAL ANIMATION
   ─────────────────────────────────────────────────────────────
   Elements with class="reveal" start invisible and translated
   down 28px.  When site.js (IntersectionObserver) adds the
   class "in", they transition to full opacity and original
   position over 0.7s with a natural ease curve.

   HERO SEQUENCE
   The hero elements (eyebrow → h1 → role → lede → CTA) use
   a separate CSS animation (@keyframes rise) with staggered
   animation-delay values so they appear one after another.
   The portrait uses @keyframes pop which also scales from 92%.

   SAFETY NET (in site.js)
   The IntersectionObserver only fires when elements scroll
   INTO view.  For above-fold content (About, Contact page
   headers), this means elements stay hidden if the page loads
   with them already visible.  site.js fires a requestAnimationFrame
   check on load that immediately adds "in" to any .reveal
   element that's already in the viewport.

   ACCESSIBILITY
   prefers-reduced-motion: reduce removes all animations and
   transitions globally and immediately shows all .reveal
   elements (opacity: 1, no transform).
   ============================================================ */
.reveal { opacity: 0; transform: translateY(28px); transition: opacity .7s cubic-bezier(.2,.7,.2,1), transform .7s cubic-bezier(.2,.7,.2,1); }
.reveal.in { opacity: 1; transform: none; }

/* Hero staggered entrance — separate keyframe animation on each element */

   ─────────────────────────────────────────────────────────────
   Two breakpoints:
   ≤ 900px — tablet / large mobile  (most multi-column grids collapse)
   ≤ 560px — small mobile           (tighter padding, single-column forms)

   900px CHANGES
   • Hero grid → single column (portrait moves above text via order: -1)
   • Value strip → 2×2 grid instead of 4×1
   • About grid → single column; skills panel loses sticky
   • Essay grid (writing.html) → single column
   • Contact grid → single column
   • Project grid → single column (number, content, CTA stack vertically)
   • PAO label/value pairs → stacked (1-column grid)
   • Nav links → full-width dropdown panel (fixed, slides in from top)
     The hamburger button (#navToggle) becomes visible.
     .nav-links.open reveals the panel.

   560px CHANGES
   • .wrap side padding reduced (32px → 22px)
   • Section padding tightened
   • Contact form first-row (.frow) becomes single column
   • References block padding reduced
