-# Aftersummer — Design Plan
-
-## Concept
-A single-page web app showing temporal progress across multiple scales, with an optional work-time mode. Elegant, light, particle-based visuals.
-
-## Visual Design
-- Light warm background (#f7f6f2)
-- Particle accumulation: dark particles fill each card as time passes
-- Elegant sans-serif typography (Inter)
-- No raw percentages — contextual labels only ("42m remaining", "3 working days till summer")
-
-## Cards (7 total, stacked to fill viewport)
-| Card    | Normal mode                     | Work mode                              |
-|---------|---------------------------------|----------------------------------------|
-| Hour    | 0–59 min of current hour        | Same — inactive outside work hours     |
-| Day     | 00:00–23:59                     | 08:00–12:00 + 13:00–17:00 (8h)        |
-| Week    | Mon 00:00 – Sun 23:59           | Mon–Fri, work hours only               |
-| Month   | Calendar days                   | Working days in month                  |
-| Year    | Calendar days                   | Working days in year                   |
-| Summer  | Jan 1 → Midsommarafton progress | Working days — special state in summer |
-| Fall    | 1st Mon Aug → Dec 31 progress   | Working days                           |
-
-## Card States
-- **active**: dark particles accumulating
-- **not-work-time**: muted grey particles, greyed label (outside work hours/days)
-- **summer**: warm amber particles at 100% (Midsommarafton → 1st Mon Aug)
-- **off-season**: cool grey-blue particles at 0% (fall card before fall starts)
-
-## Work Rules
-- Hours: 08:00–12:00 + 13:00–17:00 (8 effective hours, lunch excluded)
-- Days: Mon–Fri
-- July: entirely off (covered by summer period)
-- Holidays: from dagsmart.se API
-- Bridge days: optional (separate toggle)
-
-## Summer / Fall Periods
-- **Summer**: Midsommarafton (from API) → first Monday of August
-- **Pre-summer**: Jan 1 → Midsommarafton
-- **Fall**: first Monday of August → Dec 31
-
-## API
-- **Base URL**: `https://api.dagsmart.se`
-- `GET /holidays?year=YEAR&weekends=false` → `[{ date, code, name: {en, sv} }]`
-  - Note: returns holidays that fall on weekends too (e.g. Easter Saturday) — must check weekends separately
-  - Midsommarafton code: `midsummerEve`
-- `GET /bridge-days?year=YEAR` → `[{ date }]` (no code/name)
-- Cached in localStorage per year, refreshed if stale (different year)
-- Proxied through local server to avoid CORS
-
-## UI Controls
-- **Work time** toggle: switches all cards to work-mode calculations
-- **Bridge days** toggle: visible only when work mode is on; treats bridge days as non-work
-
-## Stack
-- Vanilla JS (ES modules), no framework, no build step
-- Single `public/index.html` + `public/style.css` + `public/app.js`
-- Node.js + Express server: serves static files + proxies API calls
-- `npm start` to run

+# Aftersummer
+
+A minimal time-progress tracker that shows how far through the day, week, month, year — and summer — you actually are.
+
+![Aftersummer](screenshot.png)
+
+## What it does
+
+Each card represents a time period and fills with particles as time passes. No percentages — just contextual labels like "87 days till summer" or "6 days remaining".
+
+| Card   | Tracks                                                      |
+|--------|-------------------------------------------------------------|
+| Hour   | Current hour (0–59 min)                                     |
+| Day    | Current calendar day                                        |
+| Week   | Mon–Sun                                                     |
+| Month  | Calendar days in current month                              |
+| Summer | Jan 1 → Midsommarafton (Swedish midsummer eve)              |
+| Fall   | First Monday of August → Dec 31                             |
+| Year   | Jan 1 → Dec 31                                              |
+
+**Work time mode** recalculates everything in working hours (08:00–12:00, 13:00–17:00, Mon–Fri, excluding Swedish public holidays). An optional bridge days toggle treats those as non-work days too.
+
+During actual summer (Midsommarafton → first Monday of August) the Summer card turns amber and shows when you're back. The Fall card appears after that.
