Open Route 32 to Route 34, the Ruins of Alph and Azalea Town (#32)

Enable Route 32 and its Pokémon Center, the Ruins of Alph with the four
chambers, item and word rooms, inner chamber and research center, Union
Cave, Route 33, Azalea Town with Kurt's house, the kiln and Bugsy's gym,
the Slowpoke Well, Ilex Forest and Route 34.

Port what their scripts need: saved WRAM bytes by label (readmem,
writemem, loadmem: wFarfetchdPosition, wKurtApricornQuantity),
VAR_UNOWNCOUNT and VAR_KURT_APRICORNS, SelectApricornForKurt and
verbosegiveitemvar, Unown letters (GetUnownLetter, per-letter pictures,
CheckUnownLetter's redraw, UpdateUnownDex, wFirstUnownSeen), the chamber
puzzles (_UnownPuzzle), DisplayUnownWords, HoOhChamber and
OmanyteChamber.

Minigames and specials that draw a whole screen in tiles now share a
tile screen effect with ROM graphics, palettes and sprites, answered
with buttons; the standard font and textbox frame load for them.

The playthrough continues through Kurt's Slowpoke Well, Bugsy, the rival
and the Farfetch'd to the Route 34 gate; its helpers move to
tests/playthrough-driver.ts. New tests solve the Kabuto puzzle through
the world, catch Unown and make Kurt's balls.

 - Kenya's MAIL is checked as the original does, but it is given at the Route 35 gate, which is closed; its text (a 15-letter first line) is one the port's MAIL model cannot yet store. Wade's calls, rematches and gifts come with the phone (board #30).
 
+## Implemented: Route 32 to Route 34, the Ruins of Alph and Azalea Town (board #32)
+
+- Route 32 with its Pokémon Center, the Ruins of Alph (outside, the four chambers, their item and word rooms, the inner chamber and the research center) and both gates, Union Cave's three floors, Route 33, Azalea Town with its Pokémon Center, Mart, Kurt's house, the charcoal kiln and the gym, the Slowpoke Well, the Ilex Forest gates and forest, Route 34 and the Day-Care are open. Goldenrod City, Route 36 and the Pokémon Centers' second floor stay closed.
+- The story runs: the Miracle Seed, Kurt's run to the Slowpoke Well, the Rocket grunts there, the Lure Ball, Bugsy and the HIVEBADGE, the rival at Azalea's west end, the Farfetch'd herding in Ilex Forest (`wFarfetchdPosition`), HM01 from the charcoal master and the Cut tree.
+- Saved WRAM bytes that scripts read and write directly (`readmem`, `writemem`, `loadmem`) are kept by PRET label in the save's `memory` (`SAVED_WRAM`, verified by `check:reference`): so far `wFarfetchdPosition` and `wKurtApricornQuantity`.
+- Kurt makes balls: `SelectApricornForKurt` lists the apricorns in `ApricornBalls` order with their counts, asks how many with the mart's 1-99 stepper and takes them; `verbosegiveitemvar` hands over the balls the next day (`VAR_KURT_APRICORNS`, `ENGINE_KURT_MAKING_BALLS` cleared by the daily reset).
+- Unown: `GetUnownLetter` from the DVs, the per-letter front and back pictures (`UnownPicPointers`), `CheckUnownLetter`'s redraw against `UnlockedUnownLetterSets`, no wild Unown before a set is unlocked, `UpdateUnownDex` on a catch to the party or a box, `wFirstUnownSeen` (also the Pokédex's Unown picture) and `VAR_UNOWNCOUNT`.
+- The chamber puzzles (`_UnownPuzzle`) run as a tile screen with the ROM's graphics: the random border layout, the cursor's moves around START/CANCEL, picking up and placing pieces, the solved check, then the chamber's floor opens and the player falls into the inner chamber. The wall patterns (`DisplayUnownWords`) draw their word in Unown letters from the chamber's tileset in a menu box over the map. `HoOhChamber` and `OmanyteChamber` open their walls.
+- Tile screens are a general effect for minigames and specials that draw a whole Game Boy screen in tiles (`scripts/screen.ts`, `rendering/tile-screen.ts`): a tilemap with palettes and sprites, answered with buttons. `rom/font.ts` supplies the standard font and the chosen textbox frame for them.
+- `tests/playthrough.test.ts` continues through Route 32, Union Cave, Azalea Town, the Slowpoke Well, Bugsy, the rival and Ilex Forest to the Route 34 gate; its helpers now live in `tests/playthrough-driver.ts`, and `PLAYTHROUGH_SAVES` keeps each stage's save. `tests/ruins.test.ts` solves the Kabuto puzzle through the world and catches Unown; `tests/azalea.test.ts` covers Kurt's apricorns.
+- Still closed or refused here: the Day-Care's deposits and Eggs (board #29), the radios' `MapRadio` and trainers' rematch counts (board #30), the research center's `UnownPrinter` (it needs all 26 letters), the Pokédex's Unown mode, the GS Ball and Celebi shrine (not reachable without the mobile event), and sound.

 ## Native battles: current state
 
 The battle core, ROM tables, encounter hooks, battle UI and whiteout hooks are present. Unit tests cover wins, escape, loss, experience, move learning and capture; reference tests compare damage, type effectiveness, stat calculation and experience curves. Browser tests drive a test-only wild encounter through the real UI: victory with level-up and move learning, escape, whiteout, catching with a nickname, keyboard and on-screen D-pad menu navigation, mid-battle backup restore, rollback of unsupported effects, switching through the party menu and a Potion from the Items pocket. Real Route 29 encounters now use the ROM's encounter tables. Every ball can be thrown; only the contest's Park Ball handling remains.

-Meeting Mom, Elm's introduction, the starter, the aide's Potion, Route 29, Cherrygrove, Route 30's trainers, Mr. Pokémon's house, the Cherrygrove rival battle, the return to Elm, capture, the catching tutorial, the PC, the introduction's naming and clock screens, and switching and healing items in battle run now. The opening milestone is complete within the recorded acceptance boundaries. The start menu, party menu and pack now run outside battle, and Pokémon evolve. Field moves from the menu, SEL/Select and MOVE PKMN W/O MAIL run too, and the Pokégear's clock, map and phone cards, with calls to Mom and Elm, Mom's bank at home and her purchases, the trainer card with the play time, the options, Fly, Dig, Teleport and the Escape Rope, and Headbutt and Rock Smash with their encounters, every remaining field item, the fishing rods, MAIL, moving items with Select and the MOVE screen's other Pokémon. Kurt's balls are thrown too, and the battle engine handles every special battle type (board #28 is complete). Route 31, Violet City, Sprout Tower and Falkner's gym are open (board #31). The synthetic CI suite runs on the shared server runner (board #45): 143 unit tests and 10 Chromium/WebKit browser tests passed in [run 119](https://git.azuze.fr/kawa/Crystal/actions/runs/119), with ROM-dependent tests skipped. Both builds, vendor integrity and native release isolation passed too. Next roadmap milestone: the remaining Johto cities (board #32); check current board priorities before selecting work.
