Full-SVG 500 made mouse-operable for newcomers: kitty Discard button and
five-card cap, on-table phase banner, ? Help/Rules overlay with the bid
legend, legal-play dimming, card-size slider, and a layout pass that
moves the Help and size controls into the log panel so nothing overlaps.
Bump all files to 1.0.90, add NEWS, a README testing quick-start, and
make the shared engine files checkdoc-clean.
Rummy 500 gains the signature below-the-top discard pickup (T): take the
chosen card plus every card above it, melding or laying off the chosen
card at once. New `deep-pickup' class slot keeps Basic Rummy top-only;
the AI takes a buried card when it completes a new meld; the pile renders
with 0=top depth indices.
Hand & Foot gains its three missing rules: pick up the discard pile (p)
by melding the top card with two matching naturals; red threes as bonus
cards (auto-collected with a replacement draw, +100 each / +200 all four);
and the round-by-round go-down minimum (50/90/120/150) enforced as one
atomic initial meld.
Add four ERT tests (suite 111->115); refresh the README and in-file
commentary; fix cg-rum500.el's truncated file footer.
Shared hand row gains a region-tag: tagged hands carry a cg-regions click
map (cards -> (hand . i)) and a card-size slider in the same image.
cg-core adds cg-mouse-action, cg-card-click, zoom commands, cg-card-scale
(folded into cg-scale), and a cg-render-apply base for scale/zoom. Seven
hand games are now click-to-position (Scopa/Casino/Spite click-to-play),
with [mouse-1] and +/-/0 bound. Adds cgt-hand-regions; suite 111/111.
Introduce a shared meld engine and four games built on it, all on
cg-core/EIEIO with console UNICODE rendering.
* cg-rummy.el: the meld engine and Gin Rummy. Set/run validation,
candidate-meld enumeration, a bitmask-DP minimum-deadwood partition,
and a layoff finder, plus the abstract cg-rummy-game base and shared
render helpers. Gin is two-handed with draw/take/discard/knock, gin
and undercut bonuses, opponent layoffs, and play to 100.
* cg-rum500.el: the abstract cg-tablemeld-game (one mode and command
set, dispatching on the subclass) driving Basic Rummy (meld out;
score the cards left in other hands; to 100) and Rummy 500 (score the
cards you lay down, lose those left in hand; ace high and worth 15;
to 500).
* cg-handfoot.el: Hand & Foot, a partnership Canasta cousin. Hand and
foot packets, Twos and Jokers wild, rank books with clean/dirty piles,
go-out bonus, and partnership scoring to 5000. Deliberately
