v0.75.0: A new Insights tab

Your reading, all of it: the Reading studio goes back to your first read, badges say what they take, and a new
Insights tab shows what your reading adds up to. The Insights tab began as @Squeaks72's pull request
(#249), rebuilt on the app's own parts. All time and the badges are
CheetahDoesStuff's ideas (#265,
#267). Thank you both.

A new Insights tab

• A new tab (#249, from @Squeaks72), worked out from the chapters you
  have finished, each counted once:
  • At this pace: when you would finish each series you are reading, at your pace through it over the last four weeks.
  • Your best day and week.
  • Genre and source mix: this month's chapters by genre or by source, and the change since last month.
  • Series you started: how many you finished, are still reading or dropped (chapters left and nothing read in two
    months), and around which chapter you usually stop.
  • Backlog: the unread chapters of the series you have started, which hold the most and which have waited longest.
• Incognito reads are not in it, and an 18+ series is named only while Show 18+ is on.
• The pull request's other cards (when you read, the year in review, numbers on the heatmap) were left out: the Reading
  studio and Wrapped already show them.

Reading studio: All time

• All time (#265, suggested by CheetahDoesStuff). Beside 90, 180
  and 365 days, the Reading studio shows one heatmap from the day you started reading to today, up to about ten years.
  • Its days keep their size, so a long history scrolls sideways inside the card.
  • It opens on the newest weeks, in Arabic too, where the weeks run the other way.
  • The year and the month are written over the first week of each.
  • Only the heatmap: the other panels are built for a window of up to a year.

Badges say what they take

• Each badge says what it takes (#267, suggested by
  CheetahDoesStuff). Hover it, tab to it or tap it, and the line under the badges says it: Bookworm · Read 50 chapters
  · you have 40. Until you pick one, the line is about the next badge.
• Show locked lists the badges you have not earned yet, nearest first. It is off until you turn it on.
• Badges are drawn emblems now, in place of the emoji: medals of bronze, silver, gold and an aurora for the chapter
  badges, ember and moonlight for the streaks, each with its own picture. A locked one shows how close you are: a ring
  round a chapter badge, the days already done on a streak's rim, both in your accent colour. A shine passes over the
  earned ones now and then, and Legend glows; both stay still under Reduce effects or your system's reduced motion.

Phones

• The cover at the top of a series page and of Home now drifts, slowly closer and back, as it was designed to in
  v0.67.0. Until now it sat still, slightly enlarged: the animation was skipped before it began. Reduce effects or your
  system's reduced motion keep it still.

Upgrading

• Database: no changes.
• API: GET /api/stats?days=all and GET /api/stats/insights are new; see docs/api.md.

Uchiyomi Desktop (beta): downloads

Uchiyomi as a program on your own computer, for Windows and Mac. On first launch it asks how you want to
use it: on this computer (the whole app, with the library in a folder on your PC and no Docker or
server to run) or connected to your own Uchiyomi server (a window onto the server you already run).

Your computer	Download
Windows (x64)	Uchiyomi-Setup-0.75.0.exe
Mac with Apple silicon (M1 or newer)	Uchiyomi-0.75.0-arm64.dmg
Mac with an Intel processor	Uchiyomi-0.75.0-x64.dmg

Only those three are for you: the .zip, .blockmap and latest*.yml files are what the app's own updater
reads. The same installers are also here under names without a version (Uchiyomi-Setup.exe,
Uchiyomi-mac-arm64.dmg, Uchiyomi-mac-x64.dmg), which always lead to the newest release.

The app is not signed yet, so the first launch takes one extra step:

• Windows: "Windows protected your PC" appears once. Choose More info, then Run anyway. A PC
  with Smart App Control turned on blocks unsigned apps with no way past it; use the Docker install there.
• macOS: open the dmg and drag Uchiyomi to Applications. The first time you open it, macOS refuses;
  go to System Settings → Privacy & Security and choose Open Anyway.

Windows installs updates by itself. A Mac cannot update an unsigned app, so there a new version is a new
download; the menu-bar icon and Admin → Health say when one is out.

Step by step, with pictures -- which file, the first launch on each system, the two ways to use it, adding
sources, updates, backups, where files live and uninstalling:
