Open Goldenrod City, Whitney's gym and the Radio Tower quiz (#32)

Enable Goldenrod City and its buildings, the department store with its
elevator and rooftop, the Underground and its rooms, the Radio Tower
floors and the Route 35 gate.

Port what their scripts need: the herb shop, bargain shop, pharmacy and
rooftop sale marts with ROM stock, prices and text; the Name Rater; the
haircut brothers' happiness tables; the Lucky Number show over the party
and boxes with its saved number and Friday countdown (RTC day timers with
the 140-day wrap); coin and money balance boxes; Game Corner prize
registration through NewPokedexEntry; gift Pokémon to the box when the
party is full, with OT, nickname and MAIL (Kenya's 15-letter first line
now stores). Saves gain hallOfFame, timers and luckyNumber, with
defaults for older saves, and wUndergroundSwitchPositions joins the
saved script bytes.

The playthrough continues to the Bicycle, Whitney, the PLAINBADGE and the
radio card. SlotMachine and CardFlip are still refused.

+- Kenya's MAIL is checked as the original does; the Goldenrod increment below opens the Route 35 gate and adds storage of its gift text. 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 opens in the next increment below; 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`.

+- Goldenrod City and its buildings, the department store and elevator, the Underground and its connecting rooms, the Radio Tower and the Route 35 gate are open. The continuous playthrough gets the Bicycle, trains on Route 34, beats Whitney, collects the PLAINBADGE and TM45, and answers the radio card quiz.
+- The herb shop, bargain shop, pharmacy and rooftop sale use their ROM stock, prices and dialogue. Bargain stock sells once per visit and a purchase closes the shop for the day; the rooftop sale changes stock after the Hall of Fame.
+- The Name Rater checks the Pokémon's OT and ID. The haircut brothers use the ROM happiness tables. The Lucky Number show checks the party and all boxes, keeps the first winner in a prize tier, and saves its number and Friday countdown with the RTC's 140-day wrap.
+- Kenya arrives with Randy's name, ID and MAIL. Gift Pokémon can go to the current box when the party is full. Coin vendors and prize menus show the balance; a newly owned prize species shows both Pokédex entry pages before the nickname prompt. An already caught species skips registration.
+- Saves gain `hallOfFame`, `timers` and `luckyNumber`, with defaults for older saves. `wUndergroundSwitchPositions` joins the saved script bytes. Goldenrod's Pokémon Center handles the GS Ball availability check; other Battle Tower actions remain refused.
+- `tests/goldenrod.test.ts` covers shops, naming, Kenya and save reload, prize registration, Lucky Number party/box winners, save validation and boxed gifts. `tests/day-timers.test.ts` covers countdown expiry and rollover without a ROM. The 20-stage playthrough reaches Whitney and the radio card.
+- Local validation (2026-10-06): 676 unit tests passed, 3 skipped (scratch tests excluded); without a ROM, 163 passed and 516 skipped. Both builds, reference/profile checks, vendor integrity and release isolation passed. Browser checks: 157 passed, 21 skipped, 12 known WebKit menu failures (#70). CI and physical-device acceptance were not run.
+- Remaining: SlotMachine and CardFlip, radio broadcasts and rematches (#30), breeding (#29), the later Rocket takeover, routes beyond the Route 35 gate, mobile/link features and audio. This increment does not complete #32 or start #33. Boxed gifts still approximate the original stale enemy held-item byte as zero when no item is specified.

 ## 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.
 
-This is still not a complete new game. The Pokégear's radio, the Pokédex's area view, search and other modes, story progression beyond Violet City and Falkner's gym, and audio remain unfinished. The start menu opens the party menu and the pack, and Select uses the registered item, such as the Bicycle; the PCs store Pokémon, items and decorations. Surfing and terrain animation now have native implementations; later maps remain gated. Save slots, online Link, friends and real-world steps come later.
