Aeon Showcase Landing

Create a realistic, award-quality full-width desktop landing page hero 
section for a FICTIONAL knowledge management SaaS product called "AEON" 
(explicitly a sample to demonstrate fumeng's ceiling, not a real product).

Visual style: Warm editorial, pushed to absolute Dribbble-showcase 
quality. Feels hand-crafted by a senior designer at Anthropic × Notion × 
Stripe. Every pixel purposeful, every typographic choice deliberate.

Color palette (strict):
- Primary background: warm cream oklch(0.97 0.005 40) with VISIBLE paper 
  grain texture (not a flat fill)
- Deep warm ink: oklch(0.18 0.02 30)
- Accent terracotta: oklch(0.58 0.19 28)
- Warm gold foil (used in ONE spot): oklch(0.72 0.15 75)
- Muted warm grey: oklch(0.50 0.01 30)
- Hairline separator: oklch(0.88 0.008 40)

Typography (strict):
- Display: humanist serif (Tiempos Headline character), weight 500, 
  EXACT size 96px, tracking -1.5%, optical-size for display
- Body: warm editorial body serif (PP Editorial Old character), 18px, 
  line-height 1.7, weight 400
- UI labels / monospaced accents: IBM Plex Mono character, 13px 
  uppercase tracking 2%

Layout (asymmetric editorial, LEFT-aligned, 8-column text + 4-column visual):

TOP NAV (full-width, sits at the very top with 32px padding):
- Left: "AEON" wordmark in serif display 28px deep ink + a tiny 
  gold-foil seal-script stamp character "永" to the right at baseline 
  (suggesting "permanence")
- Center (spaced across): nav items in monospaced 13px uppercase: 
  "PRODUCT" · "PRICING" · "DOCS" · "JOURNAL" · "CAREERS"
- Right: "Sign in" text link in body-serif 14px + a small terracotta 
  pill button "Start writing"

HAIRLINE below nav: 1px warm-grey separator spanning full width.

HERO ROW (below hero, large whitespace breathing):

LEFT 55% (text stack):
- Eyebrow line in monospaced 13px uppercase, terracotta color:
  "A QUIET PLACE FOR DELIBERATE THOUGHT"
- 32px vertical gap
- Display headline on THREE lines (EXACT TEXT, left-aligned, 96px serif):
    "The last note-taking
    app you will ever
    adopt. Promise."
  The single word "Promise." gets a delicate WARM GOLD FOIL underline 
  (1px thin, hand-drawn feel) — the only gold accent in the entire 
  composition.
- 24px vertical gap
- Subheadline in body serif 18px, TWO lines (EXACT TEXT):
    "AEON is a workspace for people who write to think, not to publish.
    Zero noise. Zero metrics. Zero gamification."
- 32px vertical gap
- CTA row (inline):
    * Primary: terracotta pill button (36px tall, 28px horizontal 
      padding), white body-serif text 16px: "Start your first essay"
    * 24px gap
    * Secondary text link in body serif 16px deep ink with subtle 
      underline: "Watch a 90-second tour →"
- 48px vertical gap
- Trust line in monospaced 11px uppercase, muted warm grey:
    "[REPLACE WITH REAL CUSTOMER METRIC AFTER LAUNCH]"

RIGHT 45% (hero visual):
- A realistic editorial-looking note editor mockup TILTED 8 DEGREES 
  clockwise. Shows two open pages side-by-side like a spread book:
  * Left page: a handwritten-feeling essay titled "On the weight of 
    empty calendar days" in serif, with a small sketch/doodle in the 
    margin
  * Right page: continuing body text in warm serif with marginalia 
    annotations in smaller italic
- A subtle dark drop shadow beneath the editor suggests physical weight
- Small UI chrome at the top of the editor showing tabs: 
  "ESSAYS / FIELD NOTES / QUESTIONS" in tiny mono caps

BELOW HERO ROW (full-width, 96px below):

Trust bar row — SIX MONOCHROME ABSTRACT GEOMETRIC MARKS at 45% opacity, 
evenly spaced across the full width:
- circle · hexagon · square · triangle · plus · chevron
- Each has a tiny monospaced 10px label below: "[placeholder]"

Below the trust bar, a thin 1px terracotta rule spans the full width.

BACKGROUND TREATMENT:
- Warm cream paper base with visible handmade grain (not a flat fill)
- EXTREMELY faint ink-wash cherry-blossom silhouettes at 2% opacity in 
  the top-right and bottom-left corners ONLY — suggesting seasons, 
  not decoration
- A single very subtle gold-foil dot pattern running along the bottom 
  margin at 4% opacity (40 dots across the full width, 2px each)

Use case: The flagship "this is what fumeng can produce" showcase image 
for the README, 2560x1440 resolution.

STRICT CONSTRAINTS:
- NO Inter, Roboto, Arial, Space Grotesk, Fraunces, system-ui, Poppins, 
  Montserrat, DM Sans, Work Sans, Nunito anywhere.
- NO purple-pink gradients, NO tech-blue gradients, NO holographic, 
  NO glass morphism.
- NO 3-column symmetric feature grid below hero (we have NO features 
  section in this crop).
- NO emoji anywhere.
- Trust bar MUST be abstract geometric marks, NOT fabricated company 
  logos. Trust line MUST be a placeholder, NOT a made-up metric.
- All copy inside the design must be EXACTLY as specified above — 
  do not hallucinate alternative headlines or labels.
- Pixel-perfect 8px grid alignment. Letterpress restraint.
- Every decorative element must earn its place. If an element does not 
  carry meaning, it does not appear.
- Feel must be editorial, human, contemplative — NOT tech-marketing, 
  NOT corporate, NOT slick-SaaS.
