Wolves with a den, fishing, and a mixed diet

Wolves - Den: a boulder cave at the foot of the rim, sited from the seed (away from the sea and spawn, mouth toward the valley, clearing in front) - Grace period: no wolves days 1-2; they move in on day 3 and howl; hunting from night 4; pack of 2, 3 from day 6, 4 from day 9; replaced by day - Wary pack hunters: circle and dart in one at a time; a lit campfire is a safe zone, a torch makes them hesitate, walls block bites (line of sight); hit one and the pack turns; hurt wolves flee; a lone wolf is timid; by day they defend the den; home at dawn - Glowing eyes, synthesised howls, can't sleep with wolves prowling - Wolf pelt and Wolf Cloak (+25 warmth) - Animals take a committed detour around obstacles Fishing - Fishing rod (workbench); cast a float onto the lake, 1.5 s to land a bite - Perch and rarer trout; faster bites at dawn/dusk and in rain; grill them - Visible fish near the shore that jump with splash rings Mixed diet - Foods belong to meat, fish or greens; each level runs down over ~1.5 days - One group low: no healing; two low: Malnourished (health drains); all three good: Balanced diet (heal x1.5); HUD diet bars; saved Tests: test_wolves and test_fishing_diet; run_all.sh covers 9 suites

+## A cast fishing float.
+##
+## flying -> it arcs out from the rod tip.
+## floating -> it landed on deep enough water; a fish bites after a while
+##   (sooner at dawn and dusk, and in the rain).
+## biting -> the float dips; you have BITE_WINDOW seconds to reel in
+##   (Actions.reel), or the fish gets away and you wait again.
+## landed -> it fell on dry ground: nothing will bite. Reel in and try again.
+## Walking too far away snaps the line.
+##
+## A line is drawn from the rod tip each frame (hands.gd gives the tip).
