Game8 uses h4 for two opposite jobs. Persona 5 hides its entire finished
back catalogue behind nothing but an `<h4>Finished Events</h4>` inside a
collapsed accordion, so a reader blind to h4 sees one uninterrupted run of
tables and would publish fifty dead events. Genshin uses h4 the other way
round, for sub-headings *within* a single event ("Availability Period",
"Characters & Rewards for this Test Run").
So h4 now gates sections but never names one: an unrecognised h4 leaves
the current event title alone, where an unrecognised h2 or h3 still sets
it. Letting one claim the title renames "Character Test Runs" to the
label sitting above its own date table, which the Genshin fixture catches.

Scraped text becomes React content, JSON on disk and eventually SQLite
rows, so it gets cleaned at one seam: the parse wrapper in toAdapter().
Every source passes through it, a source added tomorrow is covered
without its author doing anything, and no parser can opt out — parsers
stay pure readers of one site's markup.
Removes script/style/comment content and residual tags, decodes entities
to a fixed point so an encoded tag cannot resurrect in a later decoder,
NFKC-normalises, strips control, zero-width and bidi-override characters
(an RTL override visually spoofs a title), bounds each field to the cap
the schema already declares, and requires sourceUrl to be absolute
http(s).
Three things it will not do: touch a date, drop an event it could clean
instead, or repair in silence — every repair and drop is logged by
default. Event IDs are localStorage keys, so an ID is recomputed only
when a sanitised title actually changed and the ID was minted the
standard way; all seven fixtures pass through unrepaired and
byte-identical, which is the regression guard.
Also stops decodeEntities throwing RangeError on an out-of-range
numeric reference, which would have taken a whole source's events down.

Column tables already carried a description column, but label/value detail
tables did not — Genshin events had no blurb at all. The page follows each
detail table with a sentence of prose, so take that, skipping the
call-to-action paragraphs, which are navigation rather than description.
Summary coverage goes from 13/22 events to 22/22.

Every date function returns null rather than inferring a missing year,
month or end date. A source that does not state an end yields
endsAt: null, never a plausible guess — a confidently wrong end date is
the failure this product exists to prevent.
Handles the three formats seen on Game8: "August 12, 2026",
"August 12 - September 21, 2026" (year applies to both ends, rolling the
start back when the range crosses New Year), and a slash datetime range.
Abbreviated months parse too, so a source switching to "Apr. 29" does not
silently drop events.
