description	Direction for moody premium dark pages — restaurants, hospitality, luxury services, after-hours brand worlds, refined dark SaaS, and any product that should feel late-night, considered, and exclusive. Enter through the parent pack at ../SKILL.md.

Nightside

The router opens this file when the brand should feel after-hours. Even loaded at noon, the page should read like 11pm. If the brief is "dark startup" or "tech company that happens to ship dark mode", this is the wrong direction — those go to motion-bento or modernist-grid.

Brief — when this direction fires

This direction handles work where:

• The page is after-hours — restaurant after 9pm, hotel bar, late-night brand release, jazz club, members' room.
• Premium comes from what is hidden, not what is shown. Restraint over flash.
• Photography carries the page. Light-sculpted product or environment shots at twilight.
• The brand wants to feel exclusive without ever saying "exclusive".

Typical briefs: a 24-cover restaurant, a hotel group with a flagship property, a jazz club, a single-cask whisky brand, a perfume house, a private members' club, a luxury hospitality brand, a moody premium SaaS for design-led teams.

If the brief is just "dark mode for a SaaS landing" — that's motion-bento with a dark palette, not nightside.

Calibration

Dial	Baseline	Notes
DESIGN_VARIANCE	6	Offset asymmetry; cinematic image crops; never poster-chaos
MOTION_INTENSITY	5	Slow, deliberate reveals; subtle masks; restraint over flash
VISUAL_DENSITY	3	Gallery rhythm — deep negative space, one scene per viewport

User overrides any dial inline.

Three signature moves

1. The single composed photograph

The hero of a nightside page is usually a single, perfectly lit photograph with one line of italic copy in negative space — and nothing else. No CTA. No "scroll for more" arrow. No three-column meta row.

The photograph does the work. It says: this brand is too confident to need anything else above the fold.

2. Hours and rules as luxury signal

Operational honesty reads as luxury. Lines like:

• "Tuesday to Saturday · 19:00 – late · no walk-ins"
• "Reservation by phone only. We do not take requests by email."
• "Waitlist 4 months. We will write back."
• "Six tables. Six nights a week."

These all read richer than any "Award-winning" badge. The constraint is the signal.

3. Metallic accent at small scale

The accent in a nightside palette is a muted metallic — brushed gold, copper, weathered bronze, champagne — used at very small scale (links, italicized accent words, focus rings). Saturation always under 70%.

Bright pure-color accents on dark backgrounds read as flat-black-with-neon — the AI-luxury tell. The metallic-at-small-scale move is what separates this from that tell.

Materials

Typography

• Display: italic Fraunces or Instrument Serif for romantic nightside (hospitality, restaurants, perfume); a high-contrast modern (Playfair Display, Domaine Display) for fashion-nightside; a sharp display sans (Syne, Clash Display) for contemporary dark brands.
• Body: Geist, Satoshi, DM Sans. Light weights (300–400) read richer on dark backgrounds than 500+.
• Mono: Geist Mono in small uppercase with letter-spacing: 0.2em for metadata.
• Letter-spacing: tighter on dark — display at -0.03em to -0.04em, body at -0.005em.
• Tabular numerals for prices, dates, structured data.
• Banned: Inter, Roboto, system sans as identity.

Color

• No flat black with neon. That is the AI-luxury tell.
• Backgrounds: tuned off-black, deep charcoal, deep wine, midnight ocean, warm noir.
• Surfaces: one or two steps lighter than the background, never pure white.
• Accent: a single muted metallic — #93702a (brass), #a44a2a (copper), #b8924b (brushed gold), #8e6c30 (bronze) — OR a single tonal accent — #6e2333 (burgundy), #1e2a3a (ink-navy), #3e4f3e (smoke green). Saturation always under 70%.
• Text: never pure white. Use #e8ddd3 (warm), #e6edf3 (cool), #f0ece2 (cream).
• The Lila Ban: no purple/blue glow, no violet accent, no "Vercel hero" gradients.
• Pure #000000 banned. Use #0a0a0a, #0c0c0a, #1a1612.

Layout

• Asymmetric — offset oversized title, anchored counterweight.
• Generous whitespace. Premium reads as this brand is too confident to fill every square inch.
• Banned: centered hero with three feature cards; mega-menus; tech-startup grid of "Features / Solutions / Resources".

Surface

• Cards minimally used. Surfaces are dividers, image plates, and structural negative space.
• Shadows tinted deep — never harsh black drop. Use shadows that read as ambient room light.
• Liquid-glass / glassmorphism: appropriate when justified — add border-white/10 + inset highlight for physical edge refraction.
• Image treatment: light-sculpted product crops, low-key portraits, environment shots at twilight. Photography matters more here than in any other direction.

Mandatory states

Loading: skeleton plates preserve layout. Empty in-voice ("The cellar is being restocked. Try again on Friday."). Error in-voice — never "Oops, something went wrong" placeholder. Tactile: active:scale-[0.97] with a touch slower transition (200ms instead of 160ms) — nightside responds more deliberately.

Choreography

Nightside motion is slow, deliberate, premium. Walk every animation through ../references/animation.md § 1.

Allowed

• Hero entrance: split-line fade + slow opacity over 1.4–1.8s.
• Image reveals: clip-path inset wipe + slow inner-image scale (1.15 → 1) over 1.8–2.4s — the slowest reveals in the pack.
• Velocity skew on scroll: skewY: 2deg max.
• Text masking for one or two emphasized phrases per page.
• Hover glare: glare-hover on cards, very subtle, low opacity.
• Restrained marquee if the brand calls for it — italic display, slower than cinematic-scroll's marquee (38–48s loop).

Banned in this direction

• Bouncy springs. Use cubic-bezier(0.77, 0, 0.175, 1) for slower in-out motion.
• Magnetic buttons (too SaaS — nightside CTAs are confident statements, not playful).
• Image sequences (cinematic-scroll territory).
• Aceternity meteors, sparkles, wavy-background, vortex, aurora-background — cheap shimmer, opposite of luxury.
• Fast hover transitions. Nightside hovers run 400–600ms.

Smooth scroll

Lenis appropriate; pair with subtle vignette.

Accessibility

prefers-reduced-motion strips directional motion. Color and opacity remain. Slow motion is gentler on motion-sensitive users, but the rule still applies.

Wrong-direction tells (slop specific to nightside)

Beyond the pack-wide forbidden list at ../references/forbidden.md, avoid:

• Glittery purple-blue effects — the AI-luxury tell.
• Flat black background with neon cyan or violet accent.
• Over-ornamented cards with multiple glow effects.
• Tiny luxury badges spam ("Premium", "Exclusive", "Limited", "Reserve" — all on one page).
• Generic dark startup gradients.
• Bouncy "spring" animations — wrong physics for the brand.
• Aceternity aurora-background / wavy-background / meteors — every dark-startup uses these.
• Hero text that says "Luxury redefined" / "Elevated experiences" — filler that adds nothing.
• Magnetic CTAs — wrong tone.
• Bright accent colors — saturation > 70% kills the mood.

What to push toward

• A single line of italic copy in the hero that describes a feeling, not a feature.
• One bold gesture per page (a full-bleed photograph at a chapter break, a deep-color editorial quote, a slow image mask).
• Operational honesty in copy ("Waitlist 4 months", "Six tables", "Open by appointment").
• Restraint as the dominant signal. Less is more — but only when what is there is exceptional.
• A page that would still feel premium with all motion removed.
• Real specific names, dates, addresses ("Rua dos Anjos, 4º · 1150-040 Lisboa · Tue–Sat · 19:00–late").

Reference artifact

A dedicated nightside reference artifact may live at ../examples/nightside-restaurant.html when added. Until then, calibrate against this brief:

• Open with a single twilight photograph at full-bleed, with one italic line over its lower-third in negative space.
• A short brand statement section in split layout, italic display, signed.
• An asymmetric image-led grid of 4–5 cards (rooms, wines, services, experiences) with slow image-mask reveals.
• A craft / origin section with one large captioned image and no card chrome.
• A full-width accent-color editorial quote, italic display, line-by-line reveal.
• A reservation CTA that is confident and concrete ("Reserve a table for two on Friday at 9."). Not "Book Now".
• A colophon footer with italic brand mark, address, hours by appointment, set-in (typeface credit).

Read the cinematic-scroll Maris artifact for the editorial-adjacent moves (sticky letter, deep-navy quote, colophon footer) and translate to a darker palette with a metallic accent and slower motion.
