Turning little details into everyday magic ✨

[santos @yagocom]

Kuwait moves to further amend its Nationality Law. What could the proposed changes mean for citizenship, naturalised citizens and nationality records? Key points to know.

[santos @yagocom]

The constraint against redesign matters most here—faithful interaction details are what make the device feel real, not just the visual shell

[Shubhu @positronx_]

here's exact DESIGN.md file you can use with your ai agents for designing it.

Create a single-page interactive web application that visually and behaviorally reproduces a compact retro digital handheld device.

This is NOT a creative interpretation.

This is NOT a redesign.

This is NOT an approximation.

Treat every value, dimension, color, interaction, animation, state, and visual effect in this specification as intentional and immutable.

The finished result should look like a professionally rendered physical retro electronic device sitting in the center of a nearly black screen.

The application must feel like real hardware implemented as a web interface.

0. ABSOLUTE PRIORITY

When implementing this application, follow this priority order:

Exact geometry

Exact proportions
Exact colors
Exact typography
Exact shadows / gradients / lighting
Exact pixel graphics
Exact interactions
Exact animation timing
Responsive behavior
Code cleanliness
If clean code conflicts with visual accuracy, choose visual accuracy.

If conventional UX conflicts with the specification, choose the specification.

Do not add anything that is not explicitly requested.

1. TECHNOLOGY

Build using:

React

JavaScript

CSS
HTML
SVG where explicitly specified
Web Audio API for sound effects
browser Date API for the clock
requestAnimationFrame() for stopwatch animation
Open-Meteo API for weather
Do not use a heavy UI framework.
Do not use an icon library.

Do not use an external component library.

Do not use image assets for the pixel-art graphics.

The device must be constructed using HTML/CSS/SVG and generated pixel elements.

2. PAGE / ENVIRONMENT

The entire browser viewport is the stage.

There is no:

navbar

header

footer

sidebar
page title
card wrapper
menu
additional content
The page is almost completely black.
Use:
html,
body,
# root {
width: 100%;
min-height: 100%;
}

body {
margin: 0;
padding: 0;
background: # 0c0c0e;
color: # f5f5f5;
overflow: hidden;
}

The device is centered horizontally and vertically.

Use a centered flex layout:

body {
display: flex;
align-items: center;
justify-content: center;
}
The user should immediately see the device as the sole visual object.
3. GLOBAL DESIGN LANGUAGE
The device is a fictional Japanese retro digital instrument.
Visual characteristics:
late-1990s / early-2000s portable electronics
industrial gray plastic

black recessed screen
subtle CRT characteristics
orange-red accent
monochrome pixel graphics
physical buttons
tiny technical typography
Japanese product branding
realistic plastic highlights

realistic inset shadows

subtle ambient shadow

The design must NOT look like:
a modern smartwatch
a modern dashboard
a generic calculator
a glassmorphism UI
a flat UI kit
a neumorphic web card

an iOS interface

a generic retro website

It must look like a physical object.

4. GLOBAL COLORS

Use these exact colors.

Do not substitute visually similar colors.
5. FONTS
Load these exact Google Fonts:
Space Mono
Silkscreen
Chakra Petch
Noto Sans JP
Use them as follows:
font-family: "Space Mono", monospace;
for general technical/monospaced content.
font-family: "Silkscreen", monospace;
for:
display labels
mode tabs

small technical UI text

font-family: "Chakra Petch", sans-serif;
for physical hardware labels such as:
MODE
font-family: "Noto Sans JP", sans-serif;
for:
マスタ��
Do not replace these with fallback fonts if the Google Fonts load successfully.
6. MAIN DEVICE GEOMETRY

The entire device is one physical chassis.

Desktop / base size

width: 340px
height: 480px
border-radius: 38px
padding: 16px

Larger screens

At approximately 640px+ viewport width:
width: 410px
height: 560px
border-radius: 44px
padding: 20px
The device must remain centered.

Use:
width: 340px;
height: 480px;

and:
@ media (min-width: 640px) {
width: 410px;
height: 560px;
}

Do not arbitrarily scale the entire device with transform: scale().
The actual dimensions should change at the breakpoint.

7. CHASSIS
The chassis is a rounded industrial plastic body.

Use:
background:
linear-gradient(
to bottom,
# a4a09c,
# 8c8884,
# 787571
);

Border:
border: 1px solid # 5a5856;

Main chassis shadow:
box-shadow:
0 30px 60px rgba(0,0,0,0.85),
inset 0 2px 2px rgba(255,255,255,0.7),
inset 0 -3px 4px rgba(0,0,0,0.5);

The chassis should have subtle physical depth.
Do not use a flat gray background.

8. DEVICE INTERNAL LAYOUT
Inside the chassis there are exactly two major columns:

┌──────────────────────────────┐
�� │
│ SCREEN CONTROLS│
│ │
│ SCREEN CONTROLS│
│ │
│ SCREEN CONTROLS│
│ │
└──────────────────────────────┘
Screen area:

63%
Controls area:

33%
The remaining space is the intentional gap/padding.

The controls column sits on the right.
The screen occupies almost the full vertical height.

9. SCREEN BEZEL
The screen is a deeply recessed black area.

Use:
width: 63%;
height: 100%;

Border radius:
28px

At the larger breakpoint:
32px

Padding:
12px

At larger breakpoint:
16px
Background:

# 0a0a0d

Border:

1px solid # 1c1c20

Shadow:

inset 0 4px 12px rgba(0,0,0,0.95),
inset 0 -2px 4px rgba(255,255,255,0.05),
0 2px 4px rgba(0,0,0,0.4)
The screen must look physically recessed into the chassis.
10. CRT EFFECT
Place two non-interactive overlays over the entire screen.
Scanline layer
position: absolute;
inset: 0;
pointer-events: none;
z-index: 10;
opacity: 0.70;

background-image:
repeating-linear-gradient(
to bottom,
transparent 0px,
transparent 2px,
rgba(0,0,0,0.5) 3px,
rgba(0,0,0,0.5) 4px
);

background-size: 100% 4px;

Vignette layer

position: absolute;
inset: 0;
pointer-events: none;
z-index: 10;
opacity: 0.50;

background:
radial-gradient(
circle at center,
transparent 65%,
rgba(0,0,0,0.8) 100%
);
These overlays must remain above the screen content.
11. SCREEN BRIGHTNESS

The actual screen content lives inside a brightness-controlled container.

Brightness levels:
const BRIGHTNESS_LEVELS = [100, 65, 35, 12];
Every press of the physical PWR button advances:

100 → 65 → 35 → 12 → 100

Screen opacity:
opacity: brightness / 100;
When brightness is 35 or lower:

filter: contrast(1.1) brightness(0.85);
Transition:
transition:
opacity 0.22s ease-out,
filter 0.22s ease-out;

12. LEFT POWER BUTTON

Attach a narrow physical button to the left side of the chassis.
Base dimensions:
width: 10px
height: 64px

Larger breakpoint:
width: 12px
height: 72px
Position:

left: -10px
top: 145px

Larger:
left: -12px
top: 170px
Shape:

rounded left corners

Use a horizontal metallic gradient:

linear-gradient(
to right,
# 4d4a47,
# 7d7975,
# 605d5a
)

Add:

box-shadow:
-3px 4px 10px rgba(0,0,0,0.7),
inset 0 1px 1px rgba(255,255,255,0.4);

It contains:
tiny status LED
three tiny horizontal marks
vertically rotated PWR label
LED states:
100% → green # 4ade80
65% → yellow # facc15
35% → orange # fb923c
12% → slate # 64748b

Pressing it moves the button approximately:

transform: translateX(2px);

13. POWER TOAST
When brightness changes, display a tiny pill at the top of the screen.
Background:
rgba(24,25,30,0.90)
Border:
rgba(216,90,56,0.60)

Small orange pulsing dot.

Text uses Silkscreen.

Exact messages:
PWR: HIGH 100%
PWR: MED 65%
PWR: ECO 35%
PWR: STBY 12%
Toast disappears after:
1300ms

Do not add a permanent battery indicator.

14. SCREEN CONTENT STRUCTURE
Inside the screen:
┌─────────────────────┐
│ │
│ GRAPHIC │
│ │
│ STATUS INFORMATION │
│ │
│ 00:00 │
│ │
│ DATE / HELP │
│ │
│ CLK TMR STP ALM │
│ │
└─────────────────────┘
Use a vertical flex layout:
display: flex;
flex-direction: column;
justify-content: space-between;
15. FOUR MODES

The device has exactly four operating modes:

clock
timer
stopwatch
alarm

Initial state:

clock

Mode cycle:

clock
↓
timer
↓
stopwatch
↓
alarm
↓
clock

There are three ways to change mode:
MODE hardware button
pixel brandmark
bottom mode tab
All three must trigger the same mode-changing behavior and mode sound.
16. CLOCK MODE
Clock uses browser local time.
Update every second.
Get:

const now = new Date();

Hours:
String(now.getHours()).padStart(2, "0")
Minutes:

String(now.getMinutes()).padStart(2, "0")

Seconds:
String(now.getSeconds()).padStart(2, "0")
Main display:
HH:MM
Date:
DAY MM.DD

Day abbreviations:

[
"SUN",
"MON",
"TUE",
"WED",
"THU",
"FRI",
"SAT"
]

Example:

WED 08.26

17. WEATHER

Use Open-Meteo.
Request current:
temperature_2m
is_day
weather_code
Use automatic timezone.
Refresh:
every 600000ms
= 10 minutes.
Initial fallback:
{
temp: 22,
condition: "CLEAR",
category: "sun",
isDay: true
}
Map weather codes:
if (code === 0)
return isDay
? { text: "CLEAR", category: "sun" }
: { text: "NIGHT", category: "night" };

if (code === 1 || code === 2)
return isDay
? { text: "FAIR", category: "sun" }
: { text: "CLEAR", category: "night" };

if (code === 3)
return { text: "CLOUDY", category: "cloud" };

return {
text: "CLOUDY",
category: "cloud"
};

Clock status line:

22°C • CLEAR
The temperature should be rounded to an integer.
18. PIXEL DIGIT SYSTEM

37. TIMER STATE MACHINE

Initial:

timerInitialSeconds = 300;
timerSecondsLeft = 300;
isTimerRunning = false;
UP:
next = Math.min(3599, current + 60);
DOWN:
next = Math.max(60, current - 60);
When running:
setInterval(..., 1000)
Each second:

remaining -= 1

When:
remaining <= 1
set:
running = false
remaining = 0
and play alarm.

Every time remaining is divisible by 10:
play tick
CONFIRM:
If remaining is 0:
remaining = initial

Otherwise:
running = !running

38. STOPWATCH STATE MACHINE
State:
stopwatchMs = 0;
isStopwatchRunning = false;
laps = [];
Use:
https://t.co/nGC339coXb()

for timing.

When starting:
stopwatchStartRef.current = https://t.co/nGC339coXb();
Every animation frame:

stopwatchMs =
stopwatchAccumRef.current +
(https://t.co/nGC339coXb() - stopwatchStartRef.current);

When pausing:

stopwatchAccumRef.current = stopwatchMs;

UP while running:

Create lap string:

MM:https://t.co/8fZbswINW8

Keep maximum four laps.
DOWN:
running = false
stopwatchMs = 0
accumulated = 0
laps = []
39. ALARM STATE MACHINE
Initial:
alarmHour = 7;
alarmMinute = 30;
isAlarmArmed = false;
isAlarmTriggered = false;
UP:
hour = (hour + 1) % 24;
DOWN:
minute = (minute + 5) % 60;
CONFIRM:

isAlarmArmed = !isAlarmArmed;
Every second check:
if (
isAlarmArmed &&
!isAlarmTriggered &&
now.getHours() === alarmHour &&
now.getMinutes() === alarmMinute &&
now.getSeconds() === 0
) {
isAlarmTriggered = true;
}
When triggered:
play alarm immediately
repeat alarm approximately every 1200ms
CONFIRM while ringing:
isAlarmTriggered = false
40. AUDIO SYSTEM

Create a small SoundFX class using Web Audio API.
Initialize lazily on interaction.
The sound design must be synthetic and extremely short.
POWER
sine
620Hz → 260Hz
45ms
gain 0.20
ROCKER
triangle
1200Hz → 320Hz
35ms
gain 0.14
CONFIRM
sine
380Hz → 160Hz
50ms
gain 0.22

MODE
Two tones:
1050Hz
1580Hz
separated by:
40ms
Each:
35ms
gain 0.10
LAP
sine
920Hz → 1200Hz
40ms
gain 0.12

TICK
sine
750Hz → 500Hz
15ms
gain 0.035
ALARM
Three square-wave pulses:
2048Hz
at:
0ms
80ms
160ms
Each approximately:
60ms
gain 0.15

If AudioContext is unavailable, fail silently.
41. HARDWARE SOUNDS
Every physical interaction should produce the appropriate sound.
PWR → power
MODE → mode
UP/DOWN → rocker
CONFIRM → confirm
LAP → lap
TIMER → tick
ALARM → alarm
Do not play unnecessary sounds.
42. KEYBOARD CONTROL
Implement:
ArrowUp → UP
ArrowDown → DOWN
Space → CONFIRM
Enter → CONFIRM
M → MODE
P → POWER
Prevent default behavior for these keys.

Keyboard behavior must call the same handlers as physical buttons.
Do not duplicate the logic.
43. INTERACTION PHILOSOPHY
Every physical control must visually respond to pressing.
Use subtle:
active:translate-y-[1px]
or:
active:scale-95
depending on the control.

The interaction must feel tactile but restrained.
No bounce animations.
No excessive spring physics.
No flashy transitions.
44. ANIMATION RULES
Animations should be subtle.
Allowed:
button press
screen brightness transition

toast appearance/disappearance
timer progress
stopwatch hand movement
LED pulse
pixel glow
Do NOT add:
floating particles
background animation
device rotation

3D camera movement
screen shake
flashy transitions
parallax
excessive glow
45. RESPONSIVE BEHAVIOR
At smaller viewport widths, maintain the same device design.
Do not redesign the device for mobile.
Use the smaller:
340 × 480
configuration.

At:

min-width: 640px
use:
410 × 560
configuration.
The internal proportions must remain identical.
46. TOUCH SUPPORT
All physical buttons must be clickable/tappable.
Avoid accidental text selection.
Use:
user-select: none;
-webkit-user-select: none;
Controls should have:

cursor: pointer

where appropriate.
47. ACCESSIBILITY WITHOUT CHANGING VISUALS
Buttons should have meaningful accessible labels.
Examples:
Power / Brightness
Cycle Mode
Up
Down
Start / Pause / Confirm
Use title attributes where useful.
Do NOT introduce visible accessibility UI.
48. ERROR / NETWORK FALLBACKS
Weather failure must not break the device.
Keep the fallback:
22°C • CLEAR

until fresh weather is available.

No error modal.

No toast saying “API failed.”

No broken state.
Audio failure must also be silent.
49. COMPONENT ARCHITECTURE

Use logical React components similar to:

DigitalDevice
├── Screen
│ ├── PixelWeatherGraphics
│ ├── TimerGraphic
│ ├── StopwatchGraphic
│ ├── PixelDisplay
│ └── ModeTabs
│
└── ControlsPanel
├── Brandmark
├── ModeButton
├── Rocker
├── ConfirmButton
└── JapaneseBrand
You may name components differently, but preserve this conceptual separation.
50. IMPORTANT: NO DESIGN DRIFT

The following are explicitly forbidden:

DO NOT make the device wider.

DO NOT make the device thinner.

DO NOT make the screen larger.

DO NOT make the buttons more modern.

DO NOT make the orange brighter.

DO NOT make the shadows softer.

DO NOT add glass effects.

DO NOT add gradients to the page background.

DO NOT add texture to the chassis.

DO NOT add extra labels.

DO NOT replace pixel digits with text.

DO NOT replace the pixel weather icons with SVG icons.

DO NOT replace hardware controls with generic HTML controls.

DO NOT add a title above the device.

DO NOT add a footer.

DO NOT add a settings panel.

DO NOT add extra modes.

DO NOT add extra functionality.
51. FINAL VISUAL TARGET
The final browser viewport should essentially communicate:

BLACK BACKGROUND

┌────────────────────��───┐
│ │
│ ┌──────────────┐ │
│ │ │ │
│ │ PIXEL │ MODE │
│ │ GRAPHIC │ │
│ │ │ ▲ │
│ │ 12:34 │ │
│ │ │ ▼ │
│ │ WED 08.26 │ │
│ │ CLK TMR STP │ ● │
│ └──────────────┘ │
│ │
│ マスター │
└────────────────────────┘

The device must feel like a real object,
not a website pretending to be one.

The ASCII diagram above is only conceptual.
All exact dimensions and styling values in this specification take precedence over the diagram.
