# Grounded — Design Language

Reference: an airy fitness-app look. Sage mist drifting into cream behind
everything (`AmbientBackground`), frosted glass for controls and floating
chrome (`GlassSurface`, `glassCircle`), ink type with a soft grey second
tone, painted landscapes instead of photography (`SceneArt`), a floating
glass tab bar with a dark square action button (`FloatingNav`), and one lime
spark on night-green for the primary control.

## Building blocks (`designs/`)

| Piece | Use |
|---|---|
| `AmbientBackground` | The backdrop for every light screen. |
| `GlassSurface` / `glassCircle` | Frosted panels and square controls; `onDark` over a scene or tinted stage. |
| `SceneArt` | Painted sky, sun and ridges with an optional figure glyph. Palettes come from `scenePalette(kind)`, `goalScene(accent)`, `classScene(class)`; seed with `sceneSeed(title)` so an item always wears the same picture. |
| `DotDigits` | The dotted clock in the routine player. |
| `FloatingNav` | Home's tab bar; the selected tab is a filled night block. The side action button is optional. |
| `GroundedMark` | The logo, drawn — a lime sun on a ground line under two arcs. The launcher PNGs in `assets/icons/` were rendered from the same geometry. |

Cards are image-led where an item has a kind (routines, goals, tasks): scene on
top or as a thumbnail, white type over the shaded lower half, three light
numbers along the bottom. Greetings are two-tone: Medium ink, then Regular
`colorInkSoft`. Primary buttons are square night bars with a lime icon.

`Sheet` is light (ambient) by default; passing `chrome`, `banner` or
`scene` gives a tinted stage with white type. Home, Routines and the player
build their own layouts from the same pieces.

The sections below describe the original record-style type scale, which still
applies to labels and metrics.

## Type — Inter

`TextType.Light` is Inter Display Regular (the display cut, for titles and
big numbers); Regular, Medium and Bold are Inter Regular, Medium and
SemiBold.

| Role | Family | Size | Use |
|---|---|---|---|
| Display | `TextType.Light` | 30–44 | Screen titles. Always light, never bold. |
| Title | `TextType.Bold` | 17–20 | Card and section titles. |
| Body | `TextType.Regular` | 13–14, `height: 1.5` | Descriptions, copy. |
| Label | `TextType.Bold` | 10–11, `letterSpacing: 0.8–1.2`, uppercase, `colorGrey2` | Metadata above a value. |
| Metric | `TextType.Bold` | 24–34 | Debt score, counts. |

The label/value pair is the core unit: a tiny grey all-caps label sitting
directly above a large dark value. Used everywhere numbers appear.

## Geometry

- Softly rounded, never pill-soft: large cards and image cards `16`, buttons `14`, rows, tiles and fields `12`, small controls `10`, chips and badges `8`, bars `4`. Sheets round their top at `20`.
- Portraits, the nav buttons, status dots, rings and the breathing circle are full circles.
- Screen padding `20` horizontal. Card padding `16`. Section gap `28`.
- Hairlines at `colorDivider` (black 7%), borders at `colorBorder` (black 8%).
- One soft shadow only: `0 4 18 rgba(0,0,0,0.03)`. No coloured glows.

## Colour

After the coach reference: near-black ink and buttons (`colorInk`,
`colorNight #1C1C1C`) on a neutral light grey ground (`colorAmbient*`
around `#EAEAEA`), frosted near-white cards (`colorGlassStrong`) with white
edges, and one warm orange accent (`colorAccent #EC6A36`, soft
`colorAccentSoft`). `colorLime` is that orange too: the spark on dark
buttons. Enforcement tiers keep their own colours, so standing still reads
at a glance:

| Standing | Colour |
|---|---|
| Good | green `#2F6F4E` |
| Warned | amber `#C98A04` |
| Grounded | rust `#B5442F` |
| Lockdown | oxblood `#7A1F14` |

The tier colour is used consistently — header, chip, meter, queue accent — so
the standing is legible without reading the word.

## Navigation

The nav is a floating cluster of round frosted buttons, icons only; the
open tab is a raised white disc. It switches tabs inside Home (Today,
Routines, Goals, Groups, Progress) in place: nothing is pushed, a tab has
no back arrow (`tab: true`), and Android back returns to Today. Tabs are
built on first open and then kept.

## Structure

Every screen is: black `headerBar` (back, title, action) → white sheet with a
square top edge → `sectionHeader` (label + light display title) → content.

## Rules

- Display titles are Light. Bold is for labels and metrics only.
- Numbers get a label above them, never beside them.
- Chips carry state, never actions.
- One primary button per screen; everything else is outlined or text.
- Empty states are plain. An empty overdue queue is good news, not a party.

## Home

Home opens on a light header panel (`colorHeaderTop` → `colorHeaderBottom`, text `colorHeaderText`):
greeting and avatar, a Today / Weekly toggle, a seven-day streak panel ending
today (a leaf on every kept day, kept = 80%+), then the numbers. Today shows
minutes held against planned, a ring with + that opens the "Add to today"
sheet, the plan as thumbnails, the report-card letter as the Score, and one
bar per commitment class. Weekly swaps in the week's average, a bar per day
and the class completion rates. Below the block, on the light ambient
surface: the rest of the day. Bars on the dark block use the `colorBar*` tokens.

## Groups

`see/group/`: people keeping each other honest. A group has members, shared
goals and a chat.

- **Shared goals** are split into **objectives** with a number and a unit
  (200 km, 40 runs, 30,000 words). Every member logs toward them; the card
  shows the group total, your share and a night **Log** button. Like
  personal goals, they carry no debt.
- **Leaderboard** ranks members by kept rate over the last 7 days, with
  streak, last check-in (red "quiet" after 24h) and a nudge button.
- **Chat** keeps the work and the talk together: plain messages are square
  bubbles (yours in night, others white with the author's colour), while
  check-ins (green bar) and nudges (amber bar) are cards in the thread.
  The open chat polls every 4 seconds.
- Members are drawn by `memberAvatar` / `avatarStack`
  (`designs/MemberAvatar.dart`): square painted portraits with the initial.
- Groups are reached from the nav (Groups tab), the Home "Your groups" rail
  (tap opens the chat) and the add sheet.

## Progress

`see/progress/`: progress over time, reached from the nav (Progress tab).

- A Day / Week / Month switch over one white card: routines held against
  the target, a change chip measured against the *same point* of the
  previous period, and bars (days of the week, weeks of the month) with the
  current one in night and future ones as stubs. Day shows a meter instead.
- Two tiles below: active time against its target, and the daily streak.
- Runs come from the device's run log (`RoutineRunRecord`), written when the
  routine runner logs. Targets are local (`ProgressTargets`).
- **Targets** (`TargetSetup`) is the only setup screen: routines per week,
  active minutes per week and reminders before scheduled routines. Until it
  is saved once, Progress measures against the schedule and shows a night
  "Set your weekly target" prompt. Targets never touch debt.

## Coach

`see/coach/`: the centre tab. Questions about your own data, answered by
`CoachEngine` from the run log, routines, today's plan, the overdue queue
and the debt score. There is no model and no guessing: six question kinds
(keeping routines, where you slip, streak, what's left today, active time,
debt), matched by keyword; anything else gets the list. An answer is a
frosted card with **bold** figures (`markedText`), an optional bar chart
(solid accent where the target was met, soft accent where short, a dashed
outline for the target, a callout over the standout bar) and buttons that
do something real: start a routine, open overdue, targets or progress, or
ask the follow-up. Messages fade and rise in; bars grow.
