ORAC+ per Rowan

ORAC+ gives orac2.info a modern look and adds the quality-of-life
features you'd expect from other judges.

THEMES
- Catppuccin Mocha dark theme (default) — toggle to a clean light
theme anytime from the navbar moon button
- Restyled tables, alerts, code blocks, tag badges and a sticky navbar

SUBMISSIONS HEATMAP
- GitHub/Codeforces-style grid of your last year of submissions
- Stats at a glance: submissions, problems solved (all-time, matches
the leaderboard), active days, current and longest streak
- Click any day for a popover of that day's submissions and scores
- Streak flame badge in the navbar

RANDOM PROBLEM
- One click (or Alt+R) jumps to a random unsolved problem
- Dropdown options: any problem, or rebuild the problem list

COPY CODE
- One-click copy button on code blocks, template files and
submission pages

EXTRAS
- Live filter box on the problems list
- Progress bar estimating your total problems solved (including
hidden/archived problems not shown in the problem list)
- Solve count + rough difficulty pill on every problem page

PRIVACY
No data collection, no accounts, no analytics. The extension reads
orac2.info pages and caches data locally in your browser only.

Note: heatmap, streak and solved counts need a logged-in orac2.info
session; everything else works logged out. Not affiliated with ORAC /
the Australian Maths Trust.
